[Wylug-help] vicious circular symlinks stop su (and a lot more)

[Andrew Teal]

Hello, I've had no response to previous messages -- does no-one know where I
should start?

https://www.redhat.com/mailing-lists/enigma-list/msg17168.html

The critical error is

su: error while loading shared libraries: libpam.so.0: cannot open shared
object file: Error 40

I've found that /lib/libpam.so.0 is a symbolic link to itself; I can't
delete it because I can't su to root.

AFAIK RedHat update created it. It also created (in the same directory) four
versions of libpam.so.0.75 ** and four more self-referencing symlinks:
libpam.so;3da73808 --> /lib/libpam.so;3da73808

** (each suffixed ;3da73808 or similar -- the ; stops me doing diff, but
they're the same size as the original).

Grateful for any pointers as to how to proceed ...
