Description of problem: Right now running tmpwatch on directories being labelled as samba_share_t or nfs_t leads to AVC denied messages, which might be right in the first case but it should be possible to allow it via SELinux booleans through - because we have backups on NFS that are cleaned up with tmpwatch or also a samba share for temporary files being watched by tmpwatch. Both fails as of writing due to the too strict SELinux policy. Version-Release number of selected component (if applicable): selinux-policy-targeted-3.13.1-23.el7.noarch tmpwatch-2.11-5.el7.x86_64 How reproducible: Everytime, label a directory with samba_share_t or nfs_t and run tmpwatch. Actual results: No SELinux boolean to allow tmpwatch on samba_share_t or nfs_t. Expected results: SELinux boolean to allow tmpwatch on samba_share_t or nfs_t.
