It sort of occurs to me that breaking the security contexts of things
like /etc/passwd and /bin/bash (/bin/sh) suggests to me that a much
larger problem exists.
fixfiles relabel is a time consuming process (perhaps not a big deal)
but can change things that were specifically labeled other than the
default setting, creating new issues.
# rpm -q --whatprovides /etc/passwd
(my FC-4 system)
# fixfiles -R setup restore
[root at lin-workstation activeldap]# rpm -q --whatprovides /bin/bash
(again my FC-4 system)
# fixfiles -R bash restore
