I have downgraded because more things became broken and a lot of dependencies
are shot. The message was to the effect:
Duplicate library found .... unsafe to upgrade .... remove, then try again.
The libraries sited were symlinks on /usr/ib
frist libc.so.0.6, then libdl.so.2, ehtn librt.so.1 (if I remember correctly)

I removed the symlinks requested for removal above.
Bash using its rc files no longer worked.
Without the rcfiles,as I stated, worked as non-login mode.
bash -norc or sh.

Those cited above.

Note that I did not simply remove anyting but moved it. First I took off
from /lib which of course was catastrohpic. I restored those ans was able to
reboot. That is why I say that the script should not ask users to remove
anything like that. What must be removed/replaced should be done by the
script and this should be thoroughly tested before posting, obviously. This
is unstable, ok, but not experimental.
My status with the 2.3.6 packages from stable:
1. find no longer works because it wants the newer libc6/glibc stuff. I can
downgrade that one also, I suppos. Error messages looking for glibc 2.4. No
such animal.
2. I got nvidia's driver working again after failed recompiles on the new
libc6. I can no longer do anything with the screen resolution for some
reason. Its installer has problems with its /usr/lib/tls files. Did not have
this problem before.
