Hi -
From: Carl Lowenstein <cdl(a)mpl.ucsd.edu>
I did the the same thing - wondered why I could never get a clean
file system. Then I realized what was going on.
Isn't this really true of Unix systems of any age, when doing fsck
on a mounted root file system?
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 ;)
Cheers,
Steven Schultz
