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.

Catch up on all open discussions in the Handbook namespace

 * Open discussions

As I continue to clean up our docs in 2021, 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.

Dev with docker
Clean up. Deletes all containers:

Deletes all images:

Wikidata
Wikidata implementation.

See Wikidata.

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.

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.

Prefix/Termux
Packages required to be installed in Termux (GitHub) for Gentoo Prefix to run:

Prefix/Cygwin
Packages required to be installed in Cygwin for Gentoo Prefix to run:

 * Devmanual should be added to the sites drop down menu...

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) captive portals.

Add information on enabling FreeSync on AMDGPU

Resolve PPC bootloader installation instructions
Handbook probably needs to be migrated from yaboot to GRUB2. See discussion on Handbook_Talk:PPC/Installation/Bootloader.

Pending testing with VOID Linux on a separate HDD. 11/16/2020

Add networking setup example to the Handbooks using ip command
Transision the Handbook to use the command with CIDR format rather than.

Finish new Gentoo wallpapers

 * Add new wallpapers to www.g.o. and create a package for quick and easy installation on Gentoo.
 * Work on getting a resize script for common supported display resolutions. Start with 4K, resize down as appropriate per form factor.
 * Consider mobile device resolutions. What are they?
 * Upload wallpapers sources (with attribution) to maffblaster's GitHub.
 * Cut releases on GitHub.
 * Write imagemagick resize script for end user reproducibility?
 * See this tutorial for possible options. Or this Digital Ocean article.
 * Pseudo-code from Robin:

Terminology update: Overlay -> ebuild repository
Figure out how to address the following articles (man pages will also need updated):

Layman references:


 * PORTDIR_OVERLAY variable.
 * command.

Add new recentchanges bot to #gentoo-wiki
Investigate: https://wikitech.wikimedia.org/wiki/EventStreams

Right now I'm researching mw-bot (source).

Code for a similar recentchanges output:

Waiting on a response to issue 62 to add a new wiki to the bot's command.

TODO: write a module to watch recent changes for sopel.

In Unix, what do some obscurely named commands stand for?
Link this somewhere: https://kb.iu.edu/d/abnd

Someone please work on these. Someone. ANYONE?! PLEASE!!

 * GitLab - Clean up article: meld it into proper article layout/formatting according to wiki Guidelines, review for correctness.
 * Work on bringing GitLab to Gentoo. This would be of use to infra as a GitHub fall back (since GitHub isn't nicely open source).
 * Start with a Gentoo-based container (if necessary), and build from there.
