My personal list of Article description::Gentoo stuff to do in order to get Gentoo stuff done.


 * Go to completed tasks.

Todo
Anything in the Todo category, but especially Open discussions in the Handbook namespace.

Research package mask info more easily available to sysadmins in standard package query tools
Package mask information should be easily accessible / available to system administrators using standard repo query tools. In my opinion, system adminstrators should not need to have Gentoo developer knowledge in order to determine the reason a package is masked. That reason should be more readily provided to the administrator with a query that's more accessible than with a detailed search, like in the following example.

For example, I presently see that Qt 6 is masked when I use to search for installed versions of Qt:

In order to determine why Qt is masked, the quickest query is something like the following, by using with a basic regular expression and using context to filter out the unnessary parts of the  file:

In my opinion, the only way to get this data is to have Gentoo developer knowledge:


 * 1) An understanding of ebuild repository layout.
 * 2) An understanding of where the masked package metadata is stored within the filesystem directory (which file stores package mask info).
 * 3) Decent knowledge of  - regular expressions.

What are better ways to do this?

Ebuild repository sync timestamp ISO-8601 compliant
The timestamp data (located in ) for ebuild repositories last sync time should be ISO-8601 compliant. This is an international standard and is easy to visually inspect and programmatically parse.

Perhaps create a new file in the base of the dirctory called something like or maybe even something with a more descriptive name such as ?

CPUID flags
Document how to disable CPU features by passing flag names as arguments to the  kcmdline parameter. Note that number codes from the file are also accepted by , however it is better in practice to pass the flag names since the numbers are not stable across CPU architectures. Multiple CPUID flags can specified by delimiting with commas.

It is also important to understand that using  to disable feature(s)/instruction(s) will prevent the kernel from advertising the hardware contains the offered feature(s)/instruction(s) and will prevent the kernel itself from using the feature/instruction, however it does not disable access to the feature(s)/instruction(s) from userspace. A userspace executable can still access the feature(s)/instruction(s) directly.

Handbook bootloader stuff

 * Review and merge
 * Handbook_Talk:PPC64/Installation/Bootloader
 * Maffblaster's review using PowerMac G5 hardware: TBA
 * User:Matoro/SPARCdisks with SPARC bootloader section. Close.

Better color pallet
Create 16-color pallet for a Gentoo themed shell. Base colors off official Tyrian color pallet. Used https://www.sessions.edu/color-calculator/ for color calculations.


 * 1) 48627a

Typical shell color pallet is something like:

Create community member equivalent of developer form
Members of our community would like to have "profile" pages on our wiki like our official developers do. This todo item tracks 'feature' improvement for our wiki. The following should be created to replace InfoBox user; likely cloned from existing developer resources:


 * Form:Community member
 * Form:Community member

Be sure to add the category Category:Users with profiles.

Moribund project discovery
Write SMW query to discover projects that have no leads, members, or subproject. These projects should probably be retired.

Try using #ask with #if. Check out https://www.semantic-mediawiki.org/wiki/Help:Search_range_of_pages or wildcards and in combination with CURRENTYEAR, CURRENTMONTH, CURRENTDAY magic words.

It maybe be necessary to use https://www.semantic-mediawiki.org/wiki/Extension:Semantic_Compound_Queries

TODO: Add "years, months, and days" overdue row. Need to be able to query just the YEAR, MONTH, DAY from the date datatype to make this happen.

Query moved here: Project:Gentoo/GLEP 39 election date non-compliant projects.

Set Has property description special property on existing Has properties
https://www.semantic-mediawiki.org/wiki/Help:Special_property_Has_property_description

Ease election burden
Many projects are behind on the elections. As presently defined, projects must re-elect a lead each year. In the past, has taken it upon himself to create a tracker bug with many sub-entries to track projects that are behind on elections. While was was a good effort that should not go unnoticed, it did not seem to solve the problem or motivate projects to stay on top of project election updates. Even my own project(s) were years behind (mainly because I didn't have a good situation managing my Gentoo email inbox).

TODO: Link bug where idea is discussed.

The following are a couple of proposals to help fix this:


 * 1) Amend or revise GLEP 39 to make it optional to perform a yearly election.
 * 2) * Make election date self-update (roll over) unless a project member calls for a vote.
 * 3) * Remove the requirement for annual project election; during any period past one year any existing project member has the option to call for a vote in order to appoint a new or reappoint the existing project lead(s).
 * 4)  Create automated service with info based off of the official project election data (SMW) export that will generate an email based off a templated message.
 * 5) * Message would be emailed out two weeks before the annual election date and would include current project lead, current project members... and would ask the team to vote, then update the wiki page with the new date and (new?) lead (if applicable).
 * 6) Create a website (elections.g.o or voting.g.o) that would handle elections.
 * 7) * This site could be linked from the specific project page on the wiki.
 * 8) * Site would need the ability to automatically update wiki project pages based off voting results when the election period has closed.
 * 9) * Site would need to authenticate and identify developers.
 * 10) * An automated email service could be hooked up that delivers a message to defined project email address to kick off voting two weeks before the annual election date lapses.
 * 11) Create a script on dev.g.o that handles project elections (could  be extended for this purpose?)
 * 12) * Script would need the ability to automatically update wiki project pages based off voting results when the election period has closed.
 * 13) * Pro: Authentication and identification is handled by dev.g.o.
 * 14) * Script would need a fall back path if no votes were received: I propose leaving the existing project structure as-is and automatically updating the election date. This would bring each project into compliance with how GLEP 39 without having to amend or modify the GLEP.
 * 15) * Write up documentation on script somewhere on the wiki and provide a link on each "project box" on the each respective project page.

Overlay template
The GURU community ebuild repository is official and should be supported by a template here on the wiki.

Create an Overlay template sourcing repositories from https://repos.gentoo.org/

Also, repos.g.o needs to be updated to current terminology. Layman is no longer the ebuild repo management tool of choice and is largely unmaintained.

Create Gentoo distfiles mirror docker image
Create Gentoo distfiles mirror docker image, create from a docker file?

Include a separte volume for the distfiles directory?

Protect Council and Trustee election forms, properties, and templates
It would be wise to protect council elections forms, properties, and templates:


 * Nominee
 * Nominee properties: Has Name, Has Acceptance State, Has Linked Resource, Is Council Member, Is Trustee, Is Comrel Member, Is QA Member
 * Election
 * Has Title, Has ID, Has Election Official, Has Election Infra Contact, Has Election Cutoff Date, Has Nomination Start Date, Has Start Date,
 * Other downstream properties (research)?

...

Catch up on all open discussions in the Handbook namespace

 * Open discussions

As I continue to clean up our docs in 2022, I am working to catch up with and hopefully close out all open discussions in the Handbook: namespace. Will move this section to Completed tasks when caught up to this point. Aiming for January, 2021 and plan to tackle (at least) one discussion per week, but hopefully multiple per day.

Project lead elections improvement
Provide automagic calculation based on queried project election date and current time to provide visual cue or other notification that the project needs to hold re-election... mgorny has laid the framework: Project:Gentoo/Project Lead Elections.

Gentoo handbook development and maintenance
Fork and provide updates to 's script. This will help with Handbook testing and development.

Dev with KVM/QEMU

 * 1) Verify system firmware has virtualization support enabled; setup if necessary.
 * 2) Verify KVM support is available in the system's kernel.
 * 3) Verify QEMU has been installed and configured properly for the appropriate arch(es).
 * 4) Create testing disks:
 * 5) * MBR disk on legacy x86 BIOS
 * 6) * MBR with hybrid GPT on legacy x86 BIOS.
 * 7) * GPT on legacy x86 BIOS.
 * 8) * GPT on x86_64 EFI.
 * 9) Create a VM.
 * 10) * Snapshot VM

Dev with Docker
The following repo needs copied to gitweb.g.o if it is missing: https://github.com/gentoo/gentoo-docker-images


 * 1) Get the tools:
 * 2) Start the service(s):
 * 3) * OpenRC:
 * 4) * systemd:
 * 5) When running from a Gentoo system:
 * 6) * Get a fresh copy of the gentoo:: ebuild repository:
 * 7) * Pull the stage3 image:
 * 8) * Run the a container, sharing in a copy of the freshly updated gentoo:: repo, and mounting the (512 MiB) and  (16 GiBs) directories in memory (saves SSD writes). Adjust or remove these options if the host system does not have enough memory.
 * 9) ** Alternatively, the mount command can be used, however an extra remount step is necessary in the container:
 * 10) *** When in the container,  must be removed from the  and  tmpfs mounts:
 * 11) When running from a non-Gentoo system, it is easy to also pull down a gentoo:: snapshot and mount into the container as a volume. For example:
 * 12) * Pull the images:
 * 13) * Create a volume:
 * 14) * Run the container with the volume attached
 * 1) ** Alternatively, the mount command can be used, however an extra remount step is necessary in the container:

Vocational OSS maintainer
TODO: Explain how a Gentoo developer could approach vocational full time (considered 40 hours a week) or even part time (considered at 20 hours but up to 30 hours a week) work on Gentoo.

Rationale
Audit, compliance, hardening, security, and risk assessment, etc. directly relates to the amount of time a project dedicates these various fields. In Gentoo, a security project exists to cite and inform endpoint systems of vulnerabilities related to package versions and (occasionally) security issues.

Funding (money) and time go hand-in-hand. Most developers work a primary/day job to put food on their tables and care for families. Gentoo is typically a secondary job, or hobby function. Due to this, Gentoo ends up getting the leftover daily bandwidth and minimal compute time in a developer's mind.

Really good blog entry along this theme can be found here: https://sethmlarson.dev/blog/security-for-package-maintainers

Ideas
Use GSOC as an entry point and introduction into the Gentoo ecosystem on a certain project.

Funding options
The following list are some of the methods used by open source developers to fund their efforts improving the quality of software offered (most typically) for no money:


 * https://github.com/sponsors - Gentoo developers would enroll independently; no organizational oversight.
 * https://opencollective.com

Other options include donating directly to the developer via crypto wallet address for various services, which some developers may prefer, however this generally involves transactional network fees and/or cash out conversion fees into national/fiat currencies.

Post-rsync world Handbook improvements
Looks like there are a couple of URIs available to sync the Gentoo ebuild repository via git:


 * https://github.com/gentoo-mirror/gentoo.git
 * https://gitweb.gentoo.org/repo/sync/gentoo.git

Notes from : Project:Portage/Repository_verification and Portage_Security

It would not be terribly bad idea to add an alternative section in the handbook to sync via git instead of rsync. One blocking issue is that Portage will depend upon git for runtime support... just as it depends upon rsync for runtime syncing 'out of the box' (stage) file. The difference here is that is included in the system set, whereas  is not.

IMO, Portage "sync system" dependencies should be better defined in the ebuild itself with new runtime USE flags such as,  ,  ,  ,  , and. TODO: Look at adding bitkeeper support (both to Gentoo and to Portage sync types). (See also: )

In order to obtain a copy of of the Gentoo ebuild repository in order to install git, before creating the  directory, obtain git, create the directory...

Then create the following file and.

Link developer nickname to developer map on www.g.o
This will require some investigation into the possibility of linking a name to a coordinate on www.g.o.

https://www.gentoo.org/inside-gentoo/developers/map.html

Preferable to link to a location with using an  tag such as   on the ending. The link would originate the from the LDAP generated location and point to the map.

Convert home directories to systemd homed
homed support became available in Gentoo around 2021-02-01.

Follow the upstream guide. Determine how it applies to our users and the systemd article: https://systemd.io/CONVERTING_TO_HOMED/

Rebuild and  with   support. systemd will also require  as well. Alternatively, add  in, which may help prevent additional USE flag maintenance in the future.

Enable the systemd-homed service:

Unless specifically assigned at user creation time, most single user Gentoo systems will have the primary user's ID set as 1000. Very using the following commands (according to upstream):

Create backups of important files to be modified:

Backup the user(s) home directories:

(Re)create the home directory (optionally entering the same password as the user account had before the migration):

Move the old files into the new home directory:

When the command finishes, all files will be moved into the new home directory; only empty directories will be left inside the  location. It can be finally removed with:

GDM
Although no notification is displayed on the greeter, Gnome Display Manager will prompt users to login twice...

For the time being, the best answer as to why is likely describing in. One password to authenticate the user via, which will leave the home directory unactivated. The password is needed a second time to activate the home directory (via ). If the user does not enter the password a second time (presses Enter past the second prompt; needs testing to confirm), the user will login, but HOME will be set to, which is not expected or desired.

Manual mount and repair
In case a filesystem is marked as dirty, which can happen due to disk corruption, the filesystem can be manually mounted and fsck'd. Use in order to determine filesystem is dirty.

If the check completes successfully, then the device can be mounted manually and operated on:

Moving a home directory to a new system
TODO: Verify both and  files are needed for proper home migration...

Home directories can be moved between systems by the following steps.


 * 1) Copy the home directory from the homed directory ( by default) on the old system to the homed directory on the new system.
 * 2) Copy the  and  files found under the  directory on the old system to the new system.
 * 3) Restart the systemd-homed service on the new system.
 * 4) Login on the new system.
 * 1) Login on the new system.

pam.d configuration changes
With the  flag set on pambase, three files change to add homed support. This section simply provides an overview of what changes are needed in the pam files in order to properly integrate authentication when using homed.

Create a community maintained disk space document
See this discussion. Handbook should reference basic disk space requirements, whereas community page can document in more specificity how much space is necessary for typical installations on a per-profile basis.


 * Profile space requirements
 * distfiles space requirements (btrfs) as of 2021/09/22: 282G
 * gentoo repository space requirements (btrfs) as of 2021/09/22: 562M

Should be able to hook this up to an automated export available via HTTPS somehow...

Since "desktop" profiles are becoming available, it should be possible nab uncompressed filesystem sizes from RelEng builds, this data can be used to generate a table that can be used on the main site.... alternatively link to my space on pecker.

Low disk space output
This message is also caused by low disk space as well; when there is not enough space in the ebuild's root build directory (WORKDIR) to unpack the package.

* Messages for package virtual/jpeg-0-r3:

* The ebuild phase 'unpack' has exited unexpectedly. This type of behavior * is known to be triggered by things such as failed variable assignments * (bug #190128) or bad substitution errors (bug #200313). Normally, before * exiting, bash should have displayed an error message above. If bash did * not produce an error message above, it's possible that the ebuild has * called `exit` when it should have called `die` instead. This behavior * may also be triggered by a corrupt bash binary or a hardware problem * such as memory or cpu malfunction. If the problem is not reproducible or * it appears to occur randomly, then it is likely to be triggered by a * hardware problem. If you suspect a hardware problem then you should try * some basic hardware diagnostics such as memtest. Please do not report * this as a bug unless it is consistently reproducible and you are sure * that your bash binary and hardware are functioning properly.

It would be nice to add some checks to Portage in order to better notify the user of the low space issue. At minimum add a line to the text above that mentions not enough space in WORKDIR.

Bound to fail
Using too high a MAKEOPS value and  set to   (or some other N), is a bad idea when compiling source in tmpfs or when Gentoo has been allocated only a small partition to PORTAGE_TMPDIR. In the example below the following default values are set in :

The previous example is bound to result in job failure output similar to the following:

Why does this happen?
The above occurs as explained in the OSError output from Portage: OSError: [Errno 28] No space left on device

In other words, space runs out in the directory Portage uses for compilation ( PORTAGE_TMPDIR ).

The fastest solution
Run + to close the Python interpreter, then do whatever is appropriate to obtain more disk space. Typically this can look like running and purging any failed compilations from Portage's TMPDIR:

Finally, resuming the with a smaller MAKEOPTS or jobs value (or both!) should work around the build failure:

Building stages with clang
Reddit discussion here.

This Debian sites keeps a nice list of packages that are successfully built with LLVM/Clang.

Captive portals
Explain how to access Cisco (and other annoying) captive portals that are typically present when using (at least) Chromium/FireFox and NetworkManager.

Explain how to connect to a captive portal while booted to a Gentoo admin or minimal installation media to avoid no network problems.

Nice to be able to do this via CLI as well... what tools or techniques can we come up with in order to help our community get past captive portals
