- add support for loading SELinux policy  
- add support to AMI RAID
- use System.map to determine compiled fs support
- check support for i2o
- add support for adding some custom code to linuxrc (define hooks places)
- missing module is not critical (but write big warning about this)
- tmpfs /dev hints from: https://wiki.ubuntu.com/ReplacementInit

- use dmsetup deps to find dmraid, dm-multipath, lvm2 deps:
# dmsetup deps 360060160dac01800c462f46c2e3fdb11p2
1 dependencies  : (254, 7)
# dmsetup deps 360060160dac01800c462f46c2e3fdb11
2 dependencies  : (8, 0) (8, 64)

- consider adding lzma/bzip2 support for compressing initrd image
 need to peek into System.map to be sure the support is available:
00:53:43  baggins> c052e743 T unlzma [IN]
00:54:18  baggins> c052df9a T bunzip2 [IN]
00:55:48  baggins> c052e370 T gunzip [IN]

- utilize sysfs (if avail):
(IFS=: read maj min < /sys/class/misc/device-mapper/dev; echo $maj $min)
