Considering that filesystems can be mounted ro just as quickly as they
can be remounted rw, there doesn't seem to be a lot of benefit to be
gained from attempting to use the immutable flag to protect admin level
things from admin level accounts. The immutable flag is mainly only
useful for restricting users from doing things (like changing their
.bashrc and other rather draconian measures).
