[gentoo-user] Stage-3 and profile 23.x

Post by Peter Humphrey
Hello list,
It would be good if a stage-3 tarball were available with profile 23.x built
in. Sooner or later someone will want to build a new system with such a
profile.
Is this in the offing?

It is already there; e.g.

https://mirror.bytemark.co.uk/gentoo/releases/amd64/autobuilds/
20240324T164906Z/stage3-amd64-desktop-
openrc-20240324T164906Z.tar.xz.CONTENTS.gz

From what I recall make.profile 23.0 has been available for a while now,
albeit it was previously shown as experimental (exp).

NOTE: The default OpenRC installation now assumes a merged-usr fs structure -
therefore make sure you select the appropriate profile in a new installation.

I was wondering about that. Now that we have 23.0 in place, are we meant to
change to merged-usr? Should I run the eponymous script?

That specifically says for a new installation.

From the news item:
3. If you are currently using systemd in a split-usr configuration,
then first
complete the migration to the corresponding merged-usr profile of
the
same profile version. Details on how to do this can be found in the
news
item [4].
If you are currently using openrc, migrate to 23.0 first, keeping
your disk
layout. If you want to move from split-usr to merged-usr, do that
afterwards.

You can, if you want to. I've installed sys-apps/merge-usr and ran it on my
OpenRC system, after I completed the migration to profile 23.0. It didn't
take any time at all:

I'm in the process of switching two machines fom 17.1 to
23.0/split-usr [emerge @world will probably take overnight.]

I've read the merge-usr page, and it looks pretty simple. But, I'm
going to run 23.0 split-usr for a few weeks first -- just to make sure
that the new profile hasn't broken anything. If you run OpenRC, it
doesn't sound like there's any real reason you need to do the merge
any time soon.

If you run systemd, there's some version number cutoff where it will
refuse to work on a split-usr install (IIRC). After all, the systgemd
motto is "all your computer are belong to us!"

I'd want a good reason to do so, as I can't imagine it being reversed easily -
I'd need to keep a backup of /bin, /usr and so on which I could restore if
necessary, then run emerge -e @world and save those directories again. Not
worth the candle.

There being no foreseeable prospect of the systemd bandwagon picking me up on
its way by, I think I'll stick to what I know*.

The reason for a unified filesystem layout is to align Linux with Unix (Open
Solaris) and increase compatibility between distributions, which in turn makes
it easier to install/run various tools with hardcoded paths. It also makes it
easier to separate OS Vs user binaries, while keeping the former read only, to
allow various guest OS instances to use the same host OS /usr as read only,
without treading over each other toes. I can't see why the average non-
systemd Linux desktop user will want to rush into this change for their
personal computing needs. Regardless of personal choices at this stage, the
direction of travel is towards a unified layout.
