For people that want to install gentoo, it's useful to know whether some packages (that the user wants to install) are available in uclibc or musl version (rather than standard glibc version). Reason here is that most users would want to use uclibc or musl (as uclibc and musl is faster than glibc) unless the packages he wants to include simply aren't available in uclibc/musl version. Also, even if they're not available, knowing which packages are available in uclibc/musl version is useful as he can then make a decision on what packages he wishes to swap out for other packages (that are available in uclibc/musl version).

So the question is: Is there a way to know which packages are available in uclibc/musl version (and which doesn't require having gentoo installed) ? The https://packages.gentoo.org/packages/ website doesn't seem to provide such info per package (it just tells you whether the package is available for your cpu architecture (x86, x86_64, arm, sparc, ...))

I think you have to test a package to see if it works with musl or another standard C library.

I looked at the hardened musl page, and found that there is an unhardened version -vanilla- (which is what I want).
See http://distfiles.gentoo.org/experimental/x86/musl/
The only problem here is that I'd like to have a list with everything in it, because I want to add and remove stuff as well.
I can't find such a list though (there is one for bluedragon (if you click on https://releases.freeharbor.net/ )

Are the packages in the x86 musl the same as in the amd64 musl (bluedragon) version ?
Are the packages in the x86 uclibc the same as in the hardened uclibc (lilblue) version ?
See http://distfiles.gentoo.org/releases/x86/autobuilds/current-stage3-i686-uclibc-vanilla/
and https://releases.freeharbor.net/
If not, how can I get such a list (there's a contents file I can download, but that's too detailed, I just want the programs that are installed on it)

I also can't find a uclibc stage2 ? Or Do I then just need to use the stage 2 at
https://gitweb.gentoo.org/proj/releng.git/tree/releases/weekly/specs/x86/i686 ?
I btw can't figure out what's the difference between the stage 2 livecd version and the stage 2 regular and stage 2 desktop version.

If it deviates too far from what I'm trying to achieve (depends on packages), I'll probably use a stage 2 and add uclibc later (but then what version do I use ?.

Advices that can be given varies depending on the level of the user. Currently, there is no documentation for end-users (or average users).

For example, my operating system (based on musl libc) is partially functional and not operational. I am trying to make progress and hope to arrive safely.

  • I believe you can get the list of installed packages (a posteriori) using an utility that uses the world set. The process depends on the tool used.
    Otherwise (see "Edit", below), you can view the packages installed looking at /var/db/pkg (see man portage).

Edit: I believe it is easier to get a list of installed packages and then add or remove packages as usual, e.g. emerge --unmerge.
Personally, I use pquery -I (sys-apps/pkgcore) to get the list of installed packages.
