You use ram disks for the partitions with write activities, for
example /etc and /var if you want to use FBSD you can use NanoBSD

I think it is in the order of 100,000 writes, reads are not an issue.
So with linux atime, you can very quickly get there.
I have a linux distro based on bering, which creates a ram disk and
loads all os into that on boot. config is then written out to flash
via a command.
Log files are then created in the ram disk - which does mean that
reboots they are lost but has never been a real issue for me. I tend
to use SNMP to see what the boxes are doing.

Hi folks,
When reading posts about setting up a Soekris using a compact flash, I
see a lot of people saying that a compact flash cannot withstand a lot
of writing before failing.
1.) Is that true? How much is "a lot" of writing? (My 4501 is for my
tiny, home network)
2.) How do you set up an OS (either OBSD or FBSD) to NOT write to a CF???
3.) If you set it up to not write to your CF, how does your Soekris
manage to create log files???
Thank you,
Ed
FBSD has some values you can put in your /etc/rc.conf that automatically will
create a
tmp and var dir for you on a memory files system.
tmpmfs="AUTO" # Set to YES to always create an mfs /tmp, NO to never
tmpsize="20m" # Size of mfs /tmp if created
tmpmfs_flags="-S -M" # Extra mdmfs options for the mfs /tmp
varmfs="AUTO" # Set to YES to always create an mfs /var, NO to never
varsize="32m" # Size of mfs /var if created
varmfs_flags="-S -M" # Extra mount options for the mfs /var
populate_var="AUTO" # Set to YES to always (re)populate /var, NO to never
