Package: fakeroot Version: 1.20.2-1 Severity: wishlist Hi,
while dealing with #806475 we eventually figured out that while setgroups is nooped by fakeroot, getgroups isn't handled at all. Attached is a trivial patch which lets getgroups return always a list containing only the current (faked) gid. A proper patch would likely involve saving in setgroups as well, so not marking as +patch – also as the wrapping of initgroups somehow suggests you don't want to deal with this at all. Best regards David Kalnischkies
