Then use sysvinit, and then, at your leasure, slowly move more and more
to runit.

Thousands of ways. No more PID files to go corrupt or unerased or
prematurely erased. No more 300 line init scripts: The average runit
run script has a line count in the single digits. Runit automatically
respawns everything it starts. If for some reason you want a specific
daemon not to respawn, leave that daemon in sysvinit.

Runit's easier to understand.

But please understand you can use sysvinit as PID1 and do some or all
daemon spawning and respawning from runit.

I've only run Devuan on qemu VMs.

Runit can log to the individual daemon's logs, or to syslog type stuff
if you run a logging program.

You're very welcome.
