this is what debvm does for sysvinit:

https://salsa.debian.org/helmutg/debvm/-/blob/main/share/debvm/customize-au=
tologin.sh?ref_type=3Dheads#L64

C0:2345:respawn:/sbin/getty -8 --noclear --keep-baud -a root console 115200=
,38400,9600 $TERM

The magic switch to getty is -a or --autologin which automatically logs in =
the
given user (in this case, root). When I try that on Hurd I get:

getty[621]: Bad syntax

This is the /etc/network/interfaces that debvm creates:

https://salsa.debian.org/helmutg/debvm/-/blob/main/share/debvm/customize-if=
updown.sh?ref_type=3Dheads#L15

auto /enp*=3Deth
iface eth inet dhcp

These translators exist because mmdebstrap created them:

https://gitlab.mister-muffin.de/josch/mmdebstrap/src/branch/main/mmdebstrap=
#L1107

What else could I investigate to debug whit is going on? For example in Lin=
ux
I can just run "ip link" to check which devices are even there. What do I do
on GNU/Hurd?

Thanks!

cheers, josch
