I've started thinking that I wouldn't need to abandon use of 'sv'. With
both runit and s6 installed, and a supervision tree of s6-svscan and
s6-supervise processes, I suspect that 'sv t ...' would still work. 'sv
status ...' on the other hand might not. I would need to study the control
fifo protocol and status file layout to be sure.

Again, has anyone else considered these things and can offer an opinion?
Are the differences documented anywhere? There is a certain level of
compatibility between daemontools and runit, and I presume the same exists
for s6. The devil is in the detils.
