Subject: /bin and /sbin to /usr
Date: Tue, 10 Aug 2010 14:22:30 +0300
[Following a similar discussion in another mailing list]

As you know, only a few directories can be assumed to be available after
boot[1].  Notably, /usr and /var are not among them.  Binaries in /bin
and /sbin should be enough to do basic maintanence/repair and to mount
other volumes.  Since we are using the binaries in /bin and /sbin to
potentially mount /usr, they should not depend on them.  Or can they?

On my laptop:
# for f in /bin/* /sbin/*; do if [ "$(file $f | grep ELF)" != "" ] ;
then if [ "$(ldd $f | grep /usr)" != "" ] ; then echo $(equery belongs
$f) $f; ldd $f; fi; fi; done

Questions:
1. Is this OK or should we file bugs against binaries in {/bin,/sbin} linking
against libraries in /usr/lib? Fix is relatively easy in general (give
--libdir=/lib against the config script)

2. Is the below acceptable? (symlinking from /bin to /usr/bin)
# ls -l $(find {/bin,/sbin}/ -type l)|grep /usr
lrwxrwxrwx 1 root root 20 Oct 28  2008 /bin/igawk ->
/usr/bin/igawk-3.1.6
lrwxrwxrwx 1 root root 14 Aug 10 13:29 /bin/mail -> /usr/bin/mailx
lrwxrwxrwx 1 root root 20 Oct 28  2008 /bin/pgawk ->
/usr/bin/pgawk-3.1.6

Corollary to both:  If yes, tinderbox/buildbot against other packages
are probably in order as well.

Thanks
