systemd-nspawn booting Alpine Linux fails

Hi,

I wonder if it is possible to boot Alpine Linux by systemd-nspawn.
The Alpine user mailing list can't help with this.

• root@archlinux /home/rocketmouse 
# systemd-nspawn -bqD /mnt/m1.alpine

   OpenRC 0.47.1 is starting up Linux 6.3.5-arch1-1 (x86_64) [SYSTEMD-NSPAWN]

[snip]

It's caught in an endless "can't open /dev/tty" loop.
Any ideas?

Regards,
Ralf

Re: systemd-nspawn booting Alpine Linux fails

Well - on the one hand you try to use systemd

Note: systemd-nspawn requires that the operating system in the container uses systemd init (has it running as PID 1) and systemd-nspawn is installed in the container. These requirements can be satisfied by making sure the systemd-container package is installed on the container system. The systemd-container package depends on dbus, which is not installed by default. Make sure the dbus or dbus-broker package is installed on the container system.

and Alpine uses OpenRC. It shouldn't work this way - by design.

Re: systemd-nspawn booting Alpine Linux fails

Actually, you can do it.
In your log the openrc can't open `/dev/tty`, just comment out the lines in `/etc/inittab` and add this line

console::respawn:/sbin/getty 38400 console

And here it is:
