Include all relevant user-created and user-customizable dom0 files in backups

[rootkovska]

Examples:

• net topology
• qrexec policies
• guid.conf (no longer user-customizable)
• Possibly /etc/qubes or other files inside of it (which includes the aforementioned qrexec policies) (Meaningfully backup dom0 with Qubes Backup #5608)
• Salt states (No easy way to back up Salt states in dom0 #7679)

Net topology is already included (if not, please give concrete example). Others - yes, should be.

Might be nice also to include:

• /etc/default/grub
• /etc/crontab
• /etc/crypttab
• /etc/fstab

@axon-qubes I'm not sure about those files - those are highly specific to particular installation, if you restore the backup on fresh installation, replacing those files most likely will break the system (at least because of different UUIDs)
Maybe /etc/crontab worth including.

Right, I was mainly thinking to include them in the backup but not automatically restore. But you make a good point. Perhaps it's better to leave it up to users to cp them to dom0's home before backing up.

Maybe /etc/crontab worth including.

Actually, I just checked, and my /etc/crontab has no entries, even though I have entries which show up when I do crontab -l (and they are working). So, backing up /etc/crontab would not be very useful (at least in my case).
