Hi Mark,
Thanks again for your response.

> Did you also comment out the previous tty* gettys as indicated^^^

I forgot doing it, but commenting out

1:2345:respawn:/sbin/getty 38400 tty1
...
6:23:respawn:/sbin/getty 38400 tty6

does not change the symptom.

By the way, very few people on the earth expect friendly relationship
between Devuan and systemd, and Devuan Beowulf works (almost) fine
under LXC containers, so I have no objection if this bug receives "wontfix" tag :-)

You can just tell people to use LXC...

Best regards, Ryutaroh
