Hello Dmitry,

Not sure what "getty-run" is, but indeed I don't get a TTY. But I don't even
get that far. This is my current experience:

 * Standard vmdebootstrap install of sid.
 * Install runit-init, "do as I say!", reboot (that works)
 * Boot does that:

  and hangs for 90s. Then it gets a tiny bit further:

| [ ok ] Starting SMP IRQ Balancer: irqbalance.
| [....] Starting OpenBSD Secure Shell server: sshd

And from here on, nothing. I can't log in through sshd, and there's no VT
either.

Admittedly I didn't do any RTFM, but IMHO this isn't a very friendly default
behaviour. You get locked out of your machine completely, only grub and init=
come to the rescue.

That does work now, at least immediately after installation. (Can't test on an
actual runit system). So, progress!

> Is there anything else needed for inclusion into init's pre-depends?

I wouldn't veto it, as the actual functionality for runit is not the
responsibility of the "init" metapackage. But I strongly recommend providing an
OOTB experience that gets a working system, before adding it as a pre-depends.
You should also ensure that this stays so by creating an autopkgtest that
installs runit, reboots, and makes sure that at least ssh and getty come up,
and runlevel is 2 (or 3, i. e. not S). This will ensure that this works on a
standard system, cover other architectures, and also prevent future
regressions.

Thank you!

Martin
