Systemd: how to get into rescue mode

[Volker Wysk]

Hi!

I do this:

systemctl isolate rescue.target

Then everything is closed, and I get to a virtual console. There, the
root password is queried. 

Alas, there is no reaction whatsoever. I can enter the password, but
nothing happens. Same for ctrl-d. The other virtual consoles are dead.
Alt-ctrl-del isn't recognized, too. I need to do a hard reset.

The systemctl command, above, is mentioned in an article in the German
linux magazine LinuxUser.

Any ideas?

Cheers
Volker
