When I use # rpm -Uvh disc3/Fedora/RPMS/postfix-2.0.18-4.x86_64.rpm I got many /etc/security/selinux/file_contexts: invalid context root:object_r:staff_home_xauth_t on line number 1853 /etc/security/selinux/file_contexts: invalid context system_u:object_r:default_context_t on line number 1854 /etc/security/selinux/file_contexts: invalid context system_u:object_r:amanda_recover_dir_t on line number 1855 /etc/security/selinux/file_contexts: invalid context system_u:object_r:staff_home_spamassassin_t on line number 1856
This is a policy, not an rpm, problem.
Well, if it's not an RPM problem, transfer it to whoever is responsible for the policy. Don't mark it as "WONTFIX" just because you personally won't fix it. Grumble.
