## Usually tty7 is for X.
## Qubes uses tty1 for X.

## Qubes has 'pts/0' when for example running "sudo" from a terminal emulator.
## Qubes uses 'hvc0' when using in dom0 "sudo xl console vm-name".
## When using systemd-nspawn (chroot) then `login` requires console 'console' to be permitted.

## Allow members of group `console` to use:
## - 'console'
## - 'tty1' to 'tty7'
## - 'pts/0' to 'pts/9'
## - 'hvc0' to 'hvc9'
## serial console
