To confirm, at securelevel -1, you will be able to remove immutable
files and so forth, in order to install a new kernel. At level -2 and
-3 you can no longer modify immutable files and/or change the firewall
rulesets. The latter is not so much of a problem, but the former will
effectively prevent you from installing a new kernel.
