Mandatory, but needs a default.

Mandatory?

Don't need to be provided by the user, but need to be set to a default.

Mandatory.

The last four are "mandatory" in the sense that they need to be set,
only have one correct set of values. (2,1,1,1) These are meta values to
the CRM.

Yes, all three are mandatory.

This is an oversight and not yet aligned with the actually implemented
clone code.

Anything you list below the iflabel key is probably stuff for the expert
menu.

Same here, anything below netmask is expert stuff.

raidconf is not mandatory, it can default to /etc/raidtab
