As you know, only a few directories can be assumed to be available after |
| 4 |
boot[1]. Notably, /usr and /var are not among them. Binaries in /bin |
| 5 |
and /sbin should be enough to do basic maintanence/repair and to mount |
| 6 |
other volumes. Since we are using the binaries in /bin and /sbin to |
| 7 |
potentially mount /usr, they should not depend on them. Or can they? |

On my laptop: |
| 10 |
# for f in /bin/* /sbin/*; do if [ "$(file $f | grep ELF)" != "" ] ; |
| 11 |
then if [ "$(ldd $f | grep /usr)" != "" ] ; then echo $(equery belongs |
| 12 |
$f) $f; ldd $f; fi; fi; done |

Questions: |
| 32 |
1. Is this OK or should we file bugs against binaries in {/bin,/sbin} linking |
| 33 |
against libraries in /usr/lib? Fix is relatively easy in general (give |
| 34 |
--libdir=/lib against the config script) |
| 35 |
|
| 36 |
2. Is the below acceptable? (symlinking from /bin to /usr/bin) |
| 37 |
# ls -l $(find {/bin,/sbin}/ -type l)|grep /usr |
| 38 |
lrwxrwxrwx 1 root root 20 Oct 28 2008 /bin/igawk -> |
| 39 |
/usr/bin/igawk-3.1.6 |
| 40 |
lrwxrwxrwx 1 root root 14 Aug 10 13:29 /bin/mail -> /usr/bin/mailx |
| 41 |
lrwxrwxrwx 1 root root 20 Oct 28 2008 /bin/pgawk -> |
| 42 |
/usr/bin/pgawk-3.1.6 |
| 43 |
|
| 44 |
Corollary to both: If yes, tinderbox/buildbot against other packages |
| 45 |
are probably in order as well. |
