I we are going to stop support non non-udev systems (anyone use static 
/dev today?) we can remove "modprobe/mknod" from hooks: btrfs, encrypt, 
lvm2, dmraid, and mdadm, then use on-demand module loading 
(modules.devname) (from these last four hooks there are still pending 
patches thats remove external tools (sed, cut...) usage (FS#27308 , 
FS#27307 , FS#27306 , FS#27305) we can do this in one step.
