Goran,

	The filesytem on the CF is mounted read-only (ext2).  No writes other 
than the initial flashing (hopefully).  That is why I built in 
res_config_odbc.  It also makes extensive use of ramfs for temp. 
filesystems.  Plus, if you had a 2.5" hd connected, you could use that 
for writes or a backup.  Oh yeh, the Soekris net4801 also has a USB port 
for a hard drive, etc...

	But thanks, I was under the impression that CF cards are okay as long 
as you don't write to them too often.  I will be testing them more now!
