I'm all for that since I don't seem to have any need for a home directory.
Any idea of how to do it with a passwd-file userdb backend?  I also
tried to override home directory with

 	userdb {
 		driver = passwd-file
 		args = /etc/passwd home=/bundled/home/$n
 	}

but that didn't work out too well.  Or is this feature a rephrasing of
the current topic thread "Global fields for passwd-file database".
