--- Comment #18 from Adam Williamson (Red Hat)  ---
Hrm. In a RHEL report on the same bug, Bill Nottingham noted:

"- we have systemd support for applying keys on module load (in fact, systemd
is what applies keys at boot time now, rather than a script)

So, starting in F-18, all the system defaults (such as this) have moved to
/usr/lib/sysctl.d/00-system.conf, which is read by systemd and applied at boot
(or after any necessary modules have loaded)."

which sounds like systemd should be taking care of this, but it doesn't seem to
be. CCing Bill: can you elaborate? Should systemd know to apply these settings
when the 'bridge' module is loaded? Is there a bug in systemd?
