| |
Hi,
So, I was trying to boot User-Mode Linux with a modern rootfs with systemd on it, and found that it wouldn't present me a prompt. I dug further, and found out that getty is not able to open /dev/tty1; I then tried the console-getty.service (which uses /dev/console), and it worked. The reason it doesn't work out of the box is that systemd is not able to figure out whether or not a virtual console subsystem is present: /dev/tty0 is present for some reason (although I'm not sure it's a virtual console), and this confuses systemd.
So, my question is: does um Linux have a virtual console subsystem? If so, then why doesn't it seem to work? If not, why does /dev/tty0 exist?
Thanks.
