Hello list,
I'm in a situation where I must configure a couple of soekris boxes (net4801)
with very minimal services (pf and syslogd sending all logs to a remote
server), they will be unattended and various thousands of kilometers away.
Also the system is probable to suffer electrical failures and since OBSD
is contained in a CF card I become very interested in running it over an
unique read-only partition.
The first option was add the "ro" flag to the fstab file, but it's ignored
and the system leaves the root fs in "rw" mode. The second (and desesperate)
option was add "mount -o ro /" to /etc/rc.local which seems cause a kernel
panic (no suprise here)
is it possible to have a root fs in read-only mode with OBSD?
