Hello @sleiner

I am not sure if this would really solve the problem you had encountered as you have mentioned. It would probably fail while trying to create a new group for user someone as the gid will be passed on as 1000 which is already existing.

if [ -z "$group_name" ]; then
# Group does not yet exist and will be created. Use the user name as group name.
group_name="${USERNAME}"
fi
if id -u ${USERNAME} > /dev/null 2>&1; then
# User exists, update if needed
if [ "${USER_GID}" != "automatic" ] && [ "$USER_GID" != "$(id -g $USERNAME)" ]; then
group_name="$(id -gn $USERNAME)"
groupmod --gid $USER_GID ${group_name}
usermod --gid $USER_GID $USERNAME
fi
