Yeah, but that's it: making it work by wrapping it in a
clever way. If you use it in an "imperative" way, and
then it breaks, surprise surprise.

Of course it is possible if it is possible in Elisp. If
it is possible in one way, it is possible in another
way, that does the same. That Lisp is for everything -
imperative, functional, data markup, meta
programming... - this is what makes Lisp *great*. This
"side effect"-free hysteria of Haskell etc. is an
artistic/aesthetic construction, and it has little to
do with reality.

Yes, Linux has seven runlevels, 0-6 and S. 0 is
shutdown, 1 is single user minimal (maintenance) mode
(S is plain single user mode), 2-5 are multiuser modes
which is default (and those levels can be identical),
and 6 is reboot.
In /etc/inittab, the default mode is set (usually to
2).
Each runlevel executes scripts: kill scripts are first
executed to "kill" services, then the start scripts are
executed to start services. (This is a UNIX System V
thing.)
Those scripts can be inspected with 'ls -d /etc/rc*.d'.
So, for example a reference to a startup script may
look like this:
lrwxrwxrwx 1 root 14 Jan 1 2002 S19gdm3 -> ../init.d/gdm3
For a kill script, prefix with "K" instead. The digit
to the right of S (or K) denotes the order of
execution, with the lowest number first.
If gdm3 is unwanted, it is better not to muck around
with the prefixes or otherwise rename it, instead,
follow the link and remove execution rights.
