Indeed, I'm thinking of using 2 CompactFlash ATA disks. One fully read 
only with just a small partition writable that will keep /etc/asterisk 
(astlinux mounts read-only always and only mounts read-write if you need 
to change/save the config). No worries about unclean shutdown.

The second disk I will use for voicemail, and I can swap it every year 
before it wears down.

It's probably possible to do it with another distro too but astlinux is 
already pretty much finished :) And the cost of 512 Mb or 1 GB ATA flash 
is not much more than a McDonalds meal anyways (1GB is about USD 100 now)

For voicemail I could also use a microdrive but I'm not sure what will 
happen if it breaks and * tries to read/write from it. If that would bring 
the box down it's no solution.
