# ─── ENSURES PLANK GETS ELEMENTARY'S DEFAULT DOCKITEMS ────────────────────────────

# Upstream relies on /etc/skel to initiate a new users home directory with plank's dockitems.
|
|
#
|
|
# That is not possible within nixos, but we can achieve this easily with a simple script that copies
|
|
# them. We then use a xdg autostart and initialize it during the "EarlyInitialization" phase of a gnome session
|
|
# which is most appropriate for installing files into $HOME.
