So you're saying we should handle -ENOENT specially in the initramfs?
Something like being sure we preserve errno and returning it to the
caller of selinux_init_load_policy()? That would introduce a subtle
version dependency.
Or alternatively, just try in the initramfs, ignore any errors, and
only abort if we also fail to load in the real root?
I think both of these (particularly the second) are worse than my patch
- we don't (to my knowledge) support putting policy in the initramfs
now with Fedora or Red Hat Enterprise Linux, so attempting to find it
there by default on every bootup is wrong.
To turn it around, what is the possible value in also probing the
initramfs? Does anyone out there load policy from it with systemd?
