Handbook Talk:AMD64/Installation/Media

No "current-iso" directory
The manual says "Select the current-iso/ directory", but there is none; at least not here: http://mirror.csclub.uwaterloo.ca/gentoo-distfiles/releases/amd64/autobuilds/

Unless I'm mistaken, it should be corrected to "current-install-amd64-minimal"? I can't do that myself because I lack edit permissions. ~ Michael Allan (talk) 11:05, 15 March 2015 (UTC)


 * I have fixed this a file ago. Thanks for reporting it! --Maffblaster (talk) 21:11, 18 August 2016 (UTC)

Additional Helpful Edit
The fetching of the keys example presumes a key server has already been set; for someone starting anew, this may not be the case; instead it would be more helpful if the example instruction includes specifying the key server, as well:

pgp --keyserver hkps.pool.sks-keyservers.net --recv-keys 

The previous comment was from: Jlpoole (talk)


 * It would seem that someone took this advice because the example does (now) use the hkps.pool.sks-keyservers.net server pool. Thanks for reporting it! --Maffblaster (talk) 21:15, 18 August 2016 (UTC)

Bad link for 'Gentoo AMD64 project site'
This link (in the 'Hardware requirements' paragraph) leads here: https://www.gentoo.org/proj/en/base/amd64/ and gives 404 error; the link there to the archived version of the page gives 500 error.

Booting in UEFI mode
"When installing Gentoo with the purpose of using the UEFI interface instead of BIOS, it is recommended to boot with UEFI immediately". Those words are in "Booting the installation CD" It seems as if he had to do with the installation CD, but the CD is not able UEFI. --Quilosaq (talk)


 * I believe it should be mentioned that you need to use different media like SystemRescueCD ( https://www.system-rescue-cd.org/SystemRescueCd_Homepage ) to load in UEFI and that loading in UEFI is requiered to install Gentoo which supports UEFI. - EvgeniyZh (talk)


 * You are both correct. We're working on getting the Release Engineering team to upgrade our Minimal CDs ability. Right now it can only boot in BIOS (MBR) mode. I will return here when the Handbook has been updated. Done! My edit in this section notes the Minimal install CDs inability to boot UEFI mode. It instructs the reader to use the LiveDVD instead. --Maffblaster (talk) 22:50, 20 April 2017 (UTC)

Optional:_Starting_the_SSH_daemon root login
In this section people up ssh daemon, but with latest version sshd it have #PermitRootLogin prohibit-password options by default, which allow only root login with some keys. We can add info about it to be need change sshd_config to PermitRootLogin yes

Or maybe gentoo can do it only for installation cd dvd's when prepare it ? --Cronolio (talk) 23:50, 14 June 2016 (UTC)

'Core 2' as EM64T example feels outdated
Listing Core 2 Duo & Quad processors as primary examples of EM64T CPUs seems not to be up-to-date. Core 2 is a 11 years old architecture by now (2017). Giving a Core iX as the example would fit much better.


 * Updated to Core i3, i5, and i7 for example. Please remember to sign contributions to discussion pages using the button found in the edit toolbox. Thanks! --Maffblaster (talk) 12:24, 24 April 2017 (UTC)

Typo in Note associated with: "Optional: Starting the SSH daemon"
I noticed a very minor typo in the Note associated with the SSH daemon setup.

Where it reads:

Does it not read better:

Perhaps the missing 's' comes from the use of "users" from the beginning and thus:

Things to do when a user account is added, specifically for purposes of installation assistance via ssh.
I have a laptop which will only install with physical ethernet adapter, so I intend to install via ssh from another lappy.

In doing this I noticed a few things that didn't quite follow perfectly in the handbook so I went back over it and think I can make the following observations for consideration.

Edit: I think I have created problems here by commencing the install process in a terminal session on the live CD environment, wherein one is logged in as the user gentoo. When I switch to + I am at a terminal as root, in which case the command will work as described.

Setting a root password seems to be slightly different than depicted. It appears to require sudo passwd.

I think I have this right since, the default user is gentoo and passwd would set their own password. Further, I found: passwd root, returns: passwd: you may not view or modify password information for root.

n.b. This output was copied from trying the passwd root command after I had already successfully changed it with sudo passwd, which I only tried when I couldn't do it with passwd alone (and I note that in the description, the indicated active user is indeed already root (or maybe I have something out of sequence or something - I'm trying to parse all this from the mindset of having to follow the instructions literally with little or no assumed knowledge).)

At any rate, since one needs sudo command and root user authority to perform the installation via ssh in many installation scenarios (and, if I'm not mistaken in the use case I have, where I need to conduct as much of the install as possible from my other laptop via ssh), then allowing the added user to sudo may need to be described appropriately.

Would it be enough to simply add the new user to the wheel group when creating the user for this purpose?

I have tested this from scratch - booting into the live environment switching to the + root terminal session, setting, adding a new user: and then starting  and I was able to ssh into the installation environment and execute  commands.

I used sudo vi /etc/group to add my new user to all the groups that gentoo was a member of (presumably only needs wheel) and then logged out and back in via ssh (I think the group can be updated on the fly but I didn't look up how?).

I was then able to reproduce the same experience so far using the gentoo user on the local machine with my newly added account via ssh.

I do hope I'm not wasting anyone's time with this long winded query about these aspects, as it is entirely possible I've missed something in trying to be both in the mindset of a newcomer as well as being only just knowledgeable with Gentoo to be a danger to myself and all the machines around me ;) Trying to contribute and help nonetheless. --Stardotstar (talk) 05:17, 1 July 2017 (UTC) — The preceding unsigned comment was added by Stardotstar (talk • contribs)


 * Hi, this is not the place to receive support. We only talk about improving documentation for the Handbook here. Please try getting support on the Forums, email lists, or IRC. If divulge on a different installation path than is outlined in the Handbook then you are left to your own devices and our user support. Kind regards, --Maffblaster (talk) 23:46, 25 July 2017 (UTC)

Rephrasing request
at https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Media : The occasional Gentoo LiveDVD Occasionally, a special DVD is crafted by the Gentoo Ten project which can be used to install Gentoo. The instructions further down this chapter target the Minimal Installation CD so might be a bit different. However, the LiveDVD (or any other bootable Linux environment) supports getting a root prompt by just invoking sudo su - or sudo -i in a terminal.

You should want to say: "... a special DVD is crafted by the Gento Team project ... " not the Gentoo Ten ... — The preceding unsigned comment was added by Aurelien (talk • contribs)

Better css style for 'Path' and 'c' templates
The templates and  make inline strings monospaced font. But the white spaces in that inline elements (spans) are more long than ordinary white spaces. Just an example: select to choose your iso. "open file" is a one voice, but his long space seems to join "select open" and "file to". Graphically speaking is ugly.

And this string actually presents on document: ... or  in a terminal. It's muddling: where starts or ends what?

I've looked for nice solution. The template generates span element with inline style "font-family: monospace; font-size: 95%". The template generates span element with class "tripleclick-separator" and the same style as just before. The next css code to append on head section may be a nice solution:

.tripleclick-separator,

span[style="font-family: monospace; font-size: 95%"] {

margin:0 2px;

padding:0 5px;

background:rgba(0,0,0,0.03);

border-left:1px solid #c0c0c0;

border-right:1px solid #c0c0c0;

}

The class "tripleclick-separator" is theoretically not necessary on that css code, but `span[style="font-family: monospace; font-size: 95%"]` doesn't work for ... However the method for applying style is secondary.

The long white space is 8px and I put this lenght to the left and to the right of span elements. There is a margin of 2px because near to punctuation is better. The border makes lenght, so 2 + 5 + 1 = 8px.

You can choose another solution, but now it's not good... Best regards! --Suricata (talk) 23:11, 8 September 2017 (UTC)

Shorter verification instructions
Downloaded files checksum verification instructions listed on Release media signatures are both more concise and clearer than the ones used on this page. Also approach does not require checking hashsum match manually making it more secure. Might be a good idea to use the same approach here.

Downloading Keys, Missing Keys, and Signatures not Checked
Currently, when obtaining the keys used to verify the installation image, gpg complains that 11 signatures have not been checked due to missing keys and there is 1 bad signature. From my understanding, there is no cause for concern from this but it may be wise to update the Linux verification portion of the handbook to show this message as opposed to the older output that does not show the missing keys/bad signature. --Perfectedinterest (talk) 01:41, 1 February 2019 (UTC)

Incomprehensible sentence: '... will check for no* options before do* options ... in the exact order ...'
I don't understand the sentence: 'The bootable media will check for no* options before do* options, so that options can be overridden in the exact order specified.'

What does it mean? Is the order of options important? Or will do* options override no* options in any case? When and why would I want to override options? Maybe an example would help.

Please add instruction for creating bootable USB sticks for installation.
The entire section on installation media assumes the use of a DVD-ROM. Increasingly, laptops and similar devices are supplied without any kind of optical drive. Most can, however, boot from a USB stick or similar, and USB sticks can be turned into the equivalent of a bootable CD. A recent attempt to do this demonstrated quite clearly that this is far from trivial (there seem to be any number of tools for this, but none seem to work as advertised, and many are barely maintained). Adding a section describing how to create a bootable USB stick for installation, from a few obvious environments including another Gentoo machine, would be very welcome. --Robvr (talk) 09:57, 24 April 2020 (UTC)


 * Usually I use dd to write ISO to USB flash (or isohybrid + dd). Please take a look at Category:Bootable media. --Vazhnov (talk) 10:59, 24 April 2020 (UTC)


 * I've been very pleased with the "Balena Etcher" program. You can download it for free from this web site. It's very easy to use: just put the program in the same directory as your .iso file, select it with your file manager (I use "Dolphin"), then select the image to burn and choose the stick to be used. Say start. A minute later you'll have a bootable USB stick. --Davidbryant (talk) 18:38, 29 June 2020 (UTC)
