Compressed root FS & DoC partition

Compressed root FS & DoC partition

[Dzuy Nguyen]

I have a 16MB DoC 2000.  I am able to boot make an ext2 FS on and boot 
via LILO.

Now, I want to be able to make it boot to a compressed root FS.  I've 
created my own
compressed root FS (about 6MB).  I figured I'd partition the DoC into 2 
parts of 8MB
each.  The first part is to hold the root FS (and possibly kernel) and 
the latter part an
ext2 FS to store system's configuration files (to mount on /etc later).

I've tried both using dformat and nftl_format to format half of the DoC 
and mke2fs it.
It just refuses to make the formatted half an ext2 unless the entire DoC 
is formatted.

Am I on the wrong path here?  Can someone point me to the right 
direction?  Thanks.

You could just leave the DoC formatted as a full 16MB parition and put a
kernel, config, and compressed filesystem image in there.  Then load the
compressed image as an initrd and mount your runtime config after booting.
It works on a 16MB IDE flash drive.

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.
