I'm seeing something very similar with 1.3.2 on my Performa-550.  If I 
boot into single-user and exit from there to multi-user I never see the 
problem though.  It makes me think there is some sort of timing issue at 
the time the filesystems are mounted, and I think someone else discovered 
a similar thing happening with fsck on system startup.  Possibly putting 
a delay in the rc.* scripts before the filesystem mounts will eliminate 
the problem?
