[ale] Creating Filesystem

[ChrisF at computone.com (Chris Fowler)]

I'm creating a network appliance that has roughly 20GB of disk space.?? At each
system boot, I want to recreate the filesystem on the 20GB of read writable
partition.?? The facts are below:


1.?? The space is big
2.?? It will only store trival logs that are needed
3.?? It does not need to be saved at reboot
4.?? I do not need supreblocks all over the place.


Questions
1.?? Can I use jsut 2 superblocks
2.?? Can I create a loopback image, format it, and dd just wat is needed so
?????? at bootup I can use dd instead of mke2fs?
3.?? Can I get this to happen at bootup in under 10 seconds?


Thanks,
Chris
