Oh really. No chance that Gerrit has simply taken a year or two off? Why are you using software you consider dead? Why not move to s6 if runit is dead? > try something along this lines in the source: > > #ifdef SIGPWR > /* handle that one */ > ... > #endif If it's that simple, why don't YOU do it? Someone already mentioned that BSD doesn't have this signal, so incorporating it in the wider project could be objected to by some people as non-portable.

I guess your resolution to be a little bit more friendly to each other didn't last too long. You're one guy who wants this change. You have many alternatives: * s6 * lxc.signal.halt * Patch runit yourself Everyone else: Just to express my opinion: I use runit every day and personally have no need to have it react to SIGPWR.
