Compressed root FS & DoC partition

[Dzuy Nguyen]

I don't want to store the compressed root FS on a formatted (ext2) 
partition.  The idea is to make the OS
parts that are not changing (/, /usr) "less" accessible (in flash 
memory), load and run it in memory,
and store the system's config (/etc) and logging (/var) on an ext2 so 
all writing to it will be saved.

I can dformat half of the DoC but when I mke2fs it, the nftl driver 
complains.  I can use nftl_format
portion of the DoC and mke2fs OK.  Problem is I can't make it bootable 
like dformat does, so I'll try
grub to boot instead of LILO.
