That will work fine if you select an Asterisk distro intended for such
applications, like Astlinux or Askozia. Both of these systems manage
disk acces is such a way that they maximize the lifespan of flash
media. Both are in fact intended to boot & run from much small flash
devices that are commonplace these days. They harken back to a time
when 1 GB was huge and expensive CF card.

There are many Astlinux systems out there that have been running on 64
MB CF cards in IDE adapters, and storing their configs & VM to either a
separate partition in the CF or a USB stick. I wrote this up back in
Jan 2006. http://www.mgraves.org/voip/?p=1092
