When I try to add a group to ALLOW_GROUPS in a snapper config file I get a "invalid group" error.
The issue was tracked down to getgrnam_r().
In snapper-0.3.3/snapper/AppUtil.cc get_group_gid() fails to find GID when bufsize is too small.
I have a lot of users in a group in /etc/group.
getgrnam_r() fails to return with success. Increasing bufsize from 1024 to 2000 worked. Removing some of the users from the group also helps.
I recommend to do something like described in
