I'm not yet convinced that things are that bad. Prompted by this thread I just did an 'rpm -Va' on my RHEL4 system, and got piles of S.5....T messages (accompanied by sporadic bursts of prelink activity but no error msgs - is this initiated by rpm if it thinks there is a problem?). I wrote a little script to 'rpm -V' package by package and find that: 1. I seem to have some duplicate package names (this is on an x86_64 system which has only been 'up2date'ed once immediately after installation) e.g: [root@ls1 ~]$ rpm -q tcp_wrappers tcp_wrappers-7.6-37.2 tcp_wrappers-7.6-37.2 2. almost all the entries with S.5... have a .T on the end, and that those entries are in an rpm for which all entries have a .T This suggests to me that there has been some sort of package upgrade which is not being taken into account during the verify. Looks like *something* is wrong, but quite what, I dont know. Cheers, Terry. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
