I've had this on my TODO list for a while but never got to finish it up
to the point of having a really functional system as it is quite time
consuming (especially the SELinux policy fixing part).
But I should have some time for it now so I'll try to make those packages.
Impact for non-SELinux users should be rather minimal:
* kernel: TOMOYO is already enabled and need explicit boot parameter to
operate and so will SELinux once enabled. No major changes here except
for a slightly bigger kernel.
* userspace: only a very restricted set of packages needs tweaks, but
it won't impact performance for non-SELinux users. No major changes here
except for slightly bigger packages.
Only packagers will be impacted as there are still some patches needed
and this could slow down 'core packages' updates when issues arise. But
fixes usually comes quite quickly as both Fedora and Gentoo maintain
packages with SELinux support.
I see a couple of issues that will also have to be resolved for SELinux
on Arch to be usable:
* It needs some support in pacman, otherwise package updates will be
* It needs a proper policy tuned for Arch Linux packages. Filesystem
hierarchy differences between Fedora and Arch will prevent us from just
applying the Fedora policy to Arch;
* Performance comparisons between no-SELinux and disabled-SELinux
installations to make sure the impact is minimal.
