[CentOS] Yum/RPM Update Conflicts

[Sukru TIKVES]

> error reading information on service keytable: No such file or directory

The first error seems like it's not a dependancy problem, but a missing 
file one.

If I were you, I would reinstall CentOS with the old /var not mounted 
(or mounted in something like /oldvar) and copy the necessary files 
afterwards (I guess you'd like to retain only your web pages and databases).

This way minimum amount of problems will be ensured. However there may 
be others issues while upgrading database files, since change in MySQL 
(or PostgreSQL) versions will render those imcompatible.
