Hm, maybe. In that case just not filtering the entry out of the flat
file would be good enough. In hindsight I'm not sure why we indulged
in that bit of complication anyway --- it seems unlikely that an
installation would have so many nologin roles, compared to regular ones,
that the increase in size of the flat file would be objectionable.

That *would* be the behavior if we removed the filtering.
