But this seems to be a hack, unclean in my opinion. As I got responses earlier of the year for a similar problem, Linuxulator should utilize lacking facilities from FreeBSD host system - but obviously it doesn't, especially if there are non-existent users. As I realized - and this puzzles me - there was no passwd file in my configuration, so I guess the Linuxulator has to contact the underlying FreeBSD infrastructure to get UIDs like root and others - but this seems not to be the case.
