I would consider using NetBSD instead, as that OS seems to support a stripped-down config somewhat easier than FreeBSD (or PicoBSD). I am using NetBSD on a Soekris 4801 box via CF: http://www.soekris.com/net4801.htm > The HDD to Flash adapters are around 15GBP > here and 1GB of Flash about 70GBP > > I know there are some projects around that use > Compact Flash (like Openbrick) but I was thinking > more in terms of running a stripped down desktop > workstation. > > Does CF stand lots of read / write operations ?

Many CF cards are only rated for 10K or 20K writes, although I believe that some newer CF cards will handle 50K to 100K writes. It is highly recommended that you mount filesystems read-only or at least noatime, to avoid scribbing non-significant updates to the superblock and common directories. It's also a good idea to mount /var on a RAM disk. CF is better suited for embedded applications like firewalls and the like than it is for general-purpose use. -- -Chuck
