[pve-devel] [PATCH container] fix #6392: setup: fedora: skip --prompt-new-user on firstboot

[Maximiliano Sandoval]

As per 'homectl --help':

--prompt-new-user: Query user interactively for user to create

which will wait on stdin to get the credentials for the new user, but at
this point there is no way for the user to enter such input and the
container will not start.

One could alternatively remove the unit file from the
'systemd-firstboot(1)' step, but this incantation has valid use-cases
like recognizing a existing homes on firstboot.

1. this makes no sense in the commit message ;)
2. I don't think homed integration makes a lot of sense for a system
container, and would rather skip it altogether
