After applying yesterday's rawhide to my iBook, the system is quite

seemingly failing to execute /sbin/init.
My suspicion is that a very low level library is botched (glibc or
selinux). Trying to chroot() into the system from an old YDL 3.0
install CD (the only CD what would boot on PPC I found on short
notice) fails, just producing segfaults, but YDL 3.0 is quite
old, of course, and still running 2.4. Will try and get a
FC4 install CD today and try again.
PS: The system does not use selinux.
I noticed the same thing when I updated my PowerBook yesterday. The
machine wouldn't even reboot after the 'yum update' was complete; after
'starting nash' I didn't see any output. I had to boot from an old FC4
CD and recover.
What I found was that glibc was apparently busted (everything
segfaulted), along with ld.so, libk5crypto (fixing those fixed the
'Illegal instructions' I was getting) and maybe one or two others. I
had to copy them from my boot image, install a new kernel and initrd,
and reboot to downgrade to the older glibc. I didn't see any errors
during the upgrade either, so I'm not sure what went wrong (though the
logs are probably still there).
