As in subject there is a wrong assignment for nobody-group in EXTRA_OEMESON which is `-Dnobody-group=nobody` but instead it should be `-Dnobody-group=nogroup` as everywhere `nobody` user has ids 65534:65534 and `nogroup` has 65534 id which means that `nobody` user belongs to `nogroup` group, otherwise an additional group occurs in group file.
Can you please send a patch to the list?
