[Libosinfo] debian: Various corrections

[Lasse Schuirmann]

Hello,

these patches make debian express installation more convenient. They are tested with Boxes.

[PATCH 1/3] debian: Provide reasonable recommended resources
The express installation will fail if the recommended resources are chosen without this patch.

[PATCH 2/3] debian: Allow empty passwords
The debian express installation allows setting an empty password with this patch using the very same workaround as Fedora. (Debian installer otherwise will complain about nonempty passwords.

[PATCH 3/3] debian: Add needs-internet flag for JEOS script
I found out that the JEOS script needs the internet connection too. Since this may be avoidable (I dont know if it is) a FIXME comment is included in this patch.

Greetings,

Lasse Schuirmann
