Not really. Newer systems mount the root filesystem read-only
while running fsck. After the filesystem is verified as clean
then it is upgraded to read-write.
Older systems such as 2BSD can't run with a read-only root
filesystem that I know of. At least not easily/happily. Might be
possible (the ability to upgrade a ro mount to rw is present) but
it's never been a priority to look into it ;)
