I have a question about how to use a read only root filesystem. I'm
currently working on a setup that is going to use a read-only root
filesystem and kern.securelevel set to 2. I tried booting once with
this setup and realized that I need to mount everything before I set
securelevel to 2 (not in rc.conf in other words).
I have other partitions that are mounted read-write so every file
that needs to be updated regulary resides on these partitions
(actually softlinks for motd/resolv.conf etc), but how about /dev?
Don't I need it to be read-write? I guess it's not so smart to make
it a separate partition since it will probably break stuff while
Is there a good document to read about necessary steps for a read
only root filesystem?
