Looking at your patches, and what files you are modifying, you are
enforcing this in the low-level file system.
I would love for this to be implemented in the filesystem level as
well. Something like the ext4 immutable bit, but with the ability to
still make hardlinks would be *very* useful for OSTree. And anyone
else that uses hardlinks as a data source. The vserver people do
something similiar:

At the moment I have a read-only bind mount over /usr, but what I
really want is to make the individual objects in the object store in
/ostree/repo/objects be immutable, so even if a user or app navigates
out to /sysroot they still can't mutate them (or the link targets in
the visible /usr).
