There have been several problems with this feature: - a typo; - non-existant GROUPS (even a single one) would block setting all of the supplementary groups but separately-set 'wheel'; - this feature isn't used much actually so sees no battle testing. The typo has been just fixed; GROUPS are now applied by iteration which is less effective but more reliable; an additional script hook to write down login invitation for the first passwordless account (if any) has been implemented; and several more group managing targets have been added (based on live feature's script).
