As currently I am killing most time messing with my ugly s6 jails, it's some
time I messed with PID1. As we know, quite few of the rc scripts would need to
be ported. I noticed signal handling capability in s6-svscan, and figured it is
inteded for init-like operations, but as soon as my PID1 started to run I moved
bit "below" that into userland, and I didn't try it.

Yes ofc I would be very interested in your "favorite hacks", just to
learn from it. If you don't mind.

I would be especialy interested in how you do your intial s6-svscan bootstrap as
PID1, and how you solved intial logger fifo pipe problem.
