Disk write on CF bootup

[stephenyeong]

Because nanobsd not support SMP, I must run install version on Flash.
Because running on CF, can I move all tmp file to ram disk instead of dynamic create file on Flash ?

I found rrd graph tmp & pf's rules.debug and many other tmp file create on /tmp and this path is base on root flash disk.

I want to know, can I modify fstab to make this /tmp mount from mfs ?
