I switched from /lib/udev/devices to MAKEDEV!
Understood. And in answer to Chuck's followup, I think the concern is
that because /dev is going to be mounted over we'd rather store the
static entries someplace else physically outside that mountpoint.
Complaints have been filed in bugzilla, because /lib should not
# grep -r foo /lib
could do harm!
That's a validish complaint actually. Maybe a /dev_static or something
is actually called for. Otherwise fun and games with bind mounts.
selinux does not like devices in /lib also.
Personally, I don't care what the SELinux policy does or doesn't like -
it can and should be adapted to whatever is decided :)
