# Pure-runtime deps from the session files should *NOT* be added here
# Otherwise, things like gdm pull in gnome-shell.
# gnome-settings-daemon is assumed to be >=3.27.90, but this is about
# removed components, so no need to strictly require it (older just
# won't have those daemons loaded by gnome-session).
# x11-misc/xdg-user-dirs{,-gtk} are needed to create the various XDG_*_DIRs, and
# create .config/user-dirs.dirs which is read by glib to get G_USER_DIRECTORY_*
# xdg-user-dirs-update is run during login (see 10-user-dirs-update-gnome below).
# sys-apps/dbus[X] is needed for session management.
# Our 90-xcursor-theme-gnome reads a setting from gsettings-desktop-schemas.
