I have some additional information to further clarify the mount/umount issue:
From a straight boot up, mount/umount works normally. Thanks go bad wheneverI run redhat-config-packages and attempt to install additional packages from
the distribution disks. redhat-config-packages refuses to mount the
distribution disk it is calling for. The only choice I have is to abort the
package install. There is an entry in /var/log/messages:
Sep 28 09:08:28 steverod userhelper: pam_timestamp: timestamp file `/var/run/sudo/srodgers/unknown:root' is too old, disallowing access to redhat-config-packages for UID 500
