So basically do you think it would be better for you to have "write-once flag" in
superblock
that will make all files to be unwritable (except newly created ones) as opposed to a
simple
mount option that you'd use for filesystems with non-changeable files?
(you need to mark filesystems that are in write-once mode somehow, because I think
you do not need all reiserfs filesystems to be run in this mode, right?)
Also concerning the "root should not be able to change the files", root
will be able to overwrite files by using block devices if he'd want to.
