Descriptions say what, default and notable caveats; the mkPatch calling convention is referenced from lib/default.nix instead of repeated.

# Settings shared by both sessions, and user-service handling on switch.
|
|
#
|
|
# The Steam/VR session owns the systemd user manager and the outer D-Bus
|
|
# (<runtimeDir>/bus); the nested Plasma desktop has its own XDG_RUNTIME_DIR
|
|
# and private bus. `switch` usually runs from the nested desktop, where
|
|
# home-manager's reloadSystemd is skipped ("User systemd daemon not running"),
|
|
# so `steamFrameUserServices` does it against the outer session: always
|
|
# daemon-reload, then start/stop/restart the units in `userServices`.
