Any news of s6? I'm afraid Laurent has leaved the list, either

emails from dynamic address being rejected.
My understanding is the newest thing is s6-rc, which I understand is
just like s6 except it enables ordered process startup on boot.
I've used s6. It's a heck of a lot like Runit, which I use every day,
except s6 is a tiny more sophisticated, and in s6 the process
supervisor is in PID1, not in a separate process like in Runit.

Just like Runit, s6 can easily be installed on Devuan (but not Debian),
by a fairly knowledgeable user, because the sysvinit it replaces is a
small, encapsulated module. The real beauty of this is you can "dual
init", where if your grub init reference is /sbin/init, you do a
sysvinit, whereas if it's /sbin/runit, you init via Runit. You can go
back and forth with every boot. If several Devuan users do this DIY
change of init, it will provide valuable insight into other inits, in
case at a later date Devuan decides to move off of sysvinit.
NOTE: I'd suggest installing runit or s6 direct from their projects,
and not from any Debian->Devuan packages. The packages would remove the
possibility of dual init, and the packages likely won't work.

I apologize to people who consider this topic is going a little too
far for what is the unstable version of Devuan, but, Steve, let's
consider that you can have several display managers installed, gdm3,
kdm, lightdm, slim, all of them if you want, and invoking
dpkg-reconfigure lets you choose the one in function. Similarly, dpkg
could just edit a symlink called "init". Everytime you install a new
init system dpkg asks you which one you want to be in function. Then, if
you want to bypass it, you can modify the kernel argument - I don't know
how to do that with grub2. Maybe dpkg could configure grub so as to give
you an entry for every installed init system.
