linit does less than runit since it does not respawn any subprocess,
so this may not be a good choice for runit fans.

the only solution here is to patch runit's unmaintained code and
add support for SIGPWR (similar to the way it reacts to SIGINT
(secure attention key/ctrl-alt-del)) and SIGWINCH (keyboard request).
when you are at it you can also handle other signals (e. g. the
real time signals in a way compatible with systemd).

this is highly linux-specific of course but no real problem.

that means SIGPWR cannot be replaced by another signal ?
