I did an upgrade from RedHat 9 to Fedora Core 2 from the ISO distrib. Everything went fine. After the install I ran up2date and installed all of the updates for core 2. After that I started having a problem where something in a cron will relink libc.so.6 to libc-2.2.93.so and I get errors from just about everything on the system. Heres an example of the errors trying to run ls after this happens: [root@mail root]# ls ls: /lib/libc.so.6: version `GLIBC_2.3.2' not found (required by /lib/librt.so.1) ls: /lib/libc.so.6: version `GLIBC_2.3.4' not found (required by /lib/libselinux.so.1) ls: /lib/libc.so.6: version `GLIBC_2.3.2' not found (required by /lib/libpthread.so.0) Luckily ln still works so I run "ln -sf /lib/libc-2.3.3.so /lib/libc.so.6" and all is well until the next time whatever is in cron runs again that relinks it back to libc-2.2.93.so. How can I fix this? If I don't keep a root console login I'm afraid my system will be hosed the next time this happens. TIA --- Outgoing mail is certified Virus Free.
