When creating a new user with a GID different than the UID using adduser
--encrypt-home, the GID is not passed at all from adduser to ecryptfs-
setup-private:
if (defined($encrypt_home)) {
printf gtx("Setting up encryption ...\n") if $verbose;
&systemcall($ecryptfs_setup_private, '-b', '-u', $new_name);
}
ecryptfs-setup-private then blindly chowns to $USER:$USER assuming the
GID matches the UID:
chown $USER:$USER "$CRYPTDIR" /dev/shm/.ecryptfs-$USER
(multiple chowns below this)
sc...@baka:~$ sudo adduser --encrypt-home --gid 2500 testuser
