I boot my systems off a flash IDE drive. There's a partition with just
enough of a root filesystem to make lilo work, a /boot directory with a
kernel image and memtest and an initrd.gz which is a compressed ext2
It is uncompressed into RAM and then the system runs entirely from RAM.
There is a small 2nd partition on the device which I keep a tar-file of
configuration settings. This us untarred once the system boots and fills
in things like /etc/asterisk, /var/www/docs and a few other config files,
I have a 2nd flash IDE drive for voicemail. This is mouinted as a live
filesystem and I use GSM only to store voicemail (so a 64MB device is
going to give me many hours of VM storage).
Seems to work for me and keeps writes back to the important flash device
(the boot one) to a bare minimum... I force fsck on the voicemail device
at boot time, if there are any errors and I'm working on a 'sanitiser'
too, which will remove any broken files - so it'll make sure there is a
.WAV file for every .txt file and so on. I figure losing the occasional
voicemail might be acceptable after someone pulls the plug on it. (and my
experiences of this have been good in that I've nver yet lost a file)
