There are a whole load of pieces to this particular jigsaw - getting
the kernel to mount root readonly was just part of it.
This feature is still being developed. I have just finished the
patches necessary to unmount root (which you need for ext2fs to mark
the partition as clean after a controlled shutdown); a little work
still needs to be done on the mount/unmount applications (to add the
remount option to mount and to allow umount to read the mounted files
from /etc/mtab instead of /etc/fstab), and to make sure that the fsck
programs and front end return suitable error codes if a partition
fails to check out cleanly.
The kernel support for mounting and remounting root is now all in
place. Watch this space for the final applications support - it is
not yet entirely ready.
Cheers,
Stephen Tweedie.
