Is it possible to use a pointyclicky desktoppy widgety thing to reboot
a system with runit ?  I guess from your mails you use the command

I think the reference to "sysvinit-like" from Michael Biebl is mainly
there because GNOME expects either that or systemd.  In practice you
might find that the right answer is to implement enough of `shutdown'
to satisfy GNOME.

I doubt there are many non-human callers of shutdown that use all the
exciting options, and those that do exist will probably not change
very much.

I think if I were you I would try installing a system with runit and
GNOME, make enough of an emulation that the GNOME shutdown and reboot
functions work, and call that "done".
