I created a new snapshot on which
introduces the following behaviour, which is a bit less intrusive:

If a local account is connected to a Microsoft Account, the primary
group defaults to "Users".  If it's a normal local accout it defaults
to "None", as usual.  This also covers mkpasswd from the snapshot.  

This does not work if you continue to use an already existing
/etc/passwd file.  I have no good solution for this sccenario, other
than a (yet to be written) FAQ entry.

Hope that helps nevertheless.
