[gentoo-dev] fhs and multilib question

[William Hubbs]

Hi all,

I have been dealing with a bug in openrc which prompted me to look at
our directory structure for libraries on 64 bit systems. The bug will be
referenced below[1]. The problem in the bug isn't the location of
libraries, but the fact that there is a mount point stored under the
library directories.

Here is what I've found in fhs [2].

- /lib should always exist on all architectures.
- /lib64 should only exist on amd64, ppc64, sparc64 and s390x. It
	should hold 64 bit libraries, and /lib should hold 32 bit (or 31 bit
	on s390x) libraries.
- /lib should hold 64 bit libraries on ia64.
- FHS mentions /lib32 but doesn't really define what goes in it, and with
  the definition of when /lib64 is to be used, there doesn't seem to be a
  need for /lib32.
- Also, it seems questionable that /lib is a symlink to /lib64 on
  non-multilib systems. I think we should still have separate /lib and
  /lib64 directories.

Constructive criticism of this idea, thoughts, etc, are welcome.

If there is no opposition, what would it take for us to do this?

Thanks,

William
