Bug#623577: please allow grub-pc/install_devices_empty warning to be disabled

[Marc Haber]

Package: grub-pc
Version: 1.99~rc1-12
Severity: wishlist

Hi,

as part of an automatic installation process, I would like to install
grub-pc without installing it anywhere, and non-interactively. This
doesn't work as grub insists on displaying its
grub-pc/install_devices_empty warning at critical priority after
resetting the seen flag. It thus makes sure to disrupt the automatic
process.

Please implement a possibility to get grub-pc and its dependencies
installed non-interactively even without writing the actual grub to
any disk.

Greetings
Marc
