# of your own that must run at every session start goes in ~/.xinitrc.local, which this block sources
# just before the session starts (the module's README lists where each of today's lines went).

# twice (two notifiers, two portals) and hides one copy from the other.

# and every user service see the display and the desktop's identity. An explicit list and never
# --all: a session's environment may hold things no user service should be able to read back.
