SubjectRe: dracut: ordering of modules
Hi Mimi

i'm CCing the systemd and Fedora SELinux mailing lists.

Unfortunately, the SELinux policy initialization (at least
in Fedora 16) has been moved to systemd, so, now, loading an
IMA policy cannot be done in the initial ramdisk.

Further, the SELinux policy loading code is not in a unit file
but embedded in the main binary, which means that the new code for
loading IMA policies must be added just after that point.

I already wrote a patch for this. I need some time to test it
and will post in the systemd mailing list at the beginning of
the next week.
