I have a comment for the Policy Module Packaging Guideline. The document says every *.pp files should be installed for any sort of policies (targeted, strict, mls) in the %post section. However, it can cause a problem when a part of policies are not installed yet. When we try to install an application including policy package on the system which has only targeted policy, installation of *.pp files for strict/mls will be failed no need to say. If we want to install selinux-policy-strict or -mls later, the oraphan *.pp files are not linked automatically because "/usr/bin/semodule -i" is not invoked. It will cause a simple problem, but a bit difficult to find out. I have an idea that uses "%triggerin" to invoke "/use/bin/semodule -i" to link orphan *.pp files on instllation of selinux-policy-* packages later, as follows: ---------------- %triggerin -- selinux-policy-targeted if [ $0 -eq 1 ]; then /usr/sbin/semodule -s targeted -i %{_datadir}/selinux/targeted/mymodule.pp &> /dev/null || : fi %triggerin -- selinux-policy-strict if [ $0 -eq 1 ]; then /usr/sbin/semodule -s strict -i %{_datadir}/selinux/strict/mymodule.pp &> /dev/null || : fi %triggerin -- selinux-policy-mls if [ $0 -eq 1 ]; then /usr/sbin/semodule -s mls -i %{_datadir}/selinux/mls/mymodule.pp &> /dev/null || : fi ---------------- If the application is installed on the system which already has selinux-policy-strict, "%triggerin -- selinux-policy-strict" will be invoked just when the application is installed, so there is no degrading.
