[systemd-devel] [PATCH] selinux: Only attempt to load policy exactly once, in the real root

I think the idea was

if we are not in the initrd - try to load policy
if we are in the initrd and we find selinux_path() - try to load policy

Thus embeded/thin who put everything inside the initrd will work (and
the kernel enforce=1 will mean what is should)
And where we don't put anything inside the initrd will still be
correct since we'll try to load no matter what in the real root
