This is an interesting conclusion to draw...
I use a variety of BSDs which run completely read only, so as
not to wear out the CF card.  I have around 4MB of MFS partitions
mounted for files that want to be written (DNS secondary zones,
some DHCP info, /var/run/ etc).

By NOT running the whole thing in RAM, I'm not using the
soekris's limited RAM up needlessly.

In general, though, once the machine has been up and running
for a few minutes, ALL the programs that are going to be in
use are paged into RAM. 

There's no need to put all of / into a memory file system
(and all of /var is equally silly).
