My own $0.02 is that s6-svscan -S should ignore power state signals
(including SIGINT which it currently doesn't ignore). As for which
scheme s6-linux-init-maker supports when signals are redirected, I
think using busybox is an ok default since sysvinit is on the outs and
sysvinit's use of SIGUSR1 strikes me as an unfortunate misfeature.
Cheers!
