Now that RPM packages are starting to include policy module packages (my mod_fcgid package was approved for Extras recently: http://bugzilla.redhat.com/195666), it would be nice to have a standard place for the .pp files to be dropped, and for that directory to be owned by the selinux-policy package (so that all the packages don't need to own it themselves).

I propose the following:

/usr/share/selinux/packages
(container directory, separate from modules bundled with Core package)

/usr/share/selinux/packages/mls
(policy modules for use with the mls base policy)

/usr/share/selinux/packages/strict
(policy modules for use with the strict base policy)

/usr/share/selinux/packages/targeted
(policy modules for use with the targeted base policy)

/usr/share/selinux/packages/share
(policy modules that have no base-specific elements, and can be used with all base policies)

I think this is a good idea.
There already is a standard location:

/usr/share/selinux/NAME/

Currently the selinux-policy-TYPE package looks in this directory and installs all the pp files that are in this directory. It should probably change to only install the pp files that it is packaging. This is a management headache because we don't need to manage this now. If someone has a good solution to figuring out the pp files during the spec build this would be great. Trying to update the modules-TYPE.conf file and maintaining the spec file in sync would be a royal pain.
where NAME is targeted, strict, mls, etc.

I asked about this before and it was suggested that /usr/share/selinux/NAME would best be avoided because Core/base packages would install modules there and there might be name comflicts. I'm not convinced by that argument myself, but:

* /usr/share/selinux/NAME/ is owned by selinux-policy-NAME; since most systems will have only targeted policy installed, this is an issue for packages wanting to include modules built for all base policies, which will have no directories to install strict/mls modules to. There is also no /usr/share/selinux/share directory to install policy module packages common to all base policies.

I think wherever the directory is, it needs to be owned by the selinux-policy package itself and not the subpackages.
