In prior employment we shipped a bunch of "embedded servers" with
FreeBSD on CF using Soekris hardware. What I suggest you do is rather
than duplicate your *install* CD on CF, simply use another machine to
install the desired image directly on the CF. Probably a good place to
use "dangerously dedicated" rather than a traditional MSDOS partition
FreeBSD ain't no write-only Microsoft Windows. The installed image is
robust and flexible so its easy to move one runnable image around from
one machine to the next.
CF media has a limited number of writes before the hidden magic built
into the media card starts replacing worn out blocks with spares.
Probably not a good idea to have a swap partition on your CF. Also add
"noatime" to your filesystems in /etc/fstab and do whatever you can to
minimize writing to CF.
