Allow graphical installers to use system sysinstall.
This will be used by gnome-setup to install GNOME OS and ideally installers
of other distributions talk to the same varlink interface.
Instead of failing the installation after creating the partitions and
doing almost the entire installation, and then failing if we don't have
a kernel image. Look for it before we start doing modifications to the disk.
This way we tell the user as soon as possible that we can't install the
OS because of the missing kernel image.
The three first boot screens are visually separated from the console
output before them via the "chome" and welcome strings and sufficient
whitespace. But so far they weren't from the output after them. This is
sometimes a big confusing. Let's add a bit of a separator between the
end and what comes next, too.
Just cosmetics, nothing else.
This makes sure that whenever we want to show the OS name we can show
the fancy name. Thus this moves the escaping/validation of the fancy
name out of hostnamed into generic code, and then makes use of it in
sysinstall,firstboot,prompt-util.
