Well, CF is just seen as an IDE disk. What you need to
do on the OS side
is just:
- do not swap to the CF
- do not use a journalling FS on the CF
- mount the filesystem(s) on the CF with noatime (so reads don't cause
writes)
- if you write syslog to the CF, disable synchronous writes for
the logfiles (by prepending the path in syslog.conf with -)
- optional: use tmpfs for /tmp
This is good advice, but you might also consider mounting the root fs
read only. On systems I have helped deploy we mount the CF root
read-only. /tmp & /var are a ramdisk which is built at run time.
