Hi,
in Ubuntu defaults are in X11/Xsession.d/60x11-common_xdg_path
which is shipped by x11-common and sourced by XSession
>
BTW there is some XDG_* env setting also in X11/Xsession.d/00upstart
Ok, now if only we knew what to actually use as a default for
XDG_RUNTIME_DIR; it is a per-user setting, and defining the
prefix to be /tmp/run is not enough.
Come to think of it, my choice of
${XDG_RUNTIME_DIR:-/tmp/run/$USER}
is no good, because, just as an example, if $USER comes from
an AD domain or LDAP it might contain '\'; in the least,
$USER had to undergo some transformation (escaping?) to ensure
that it's filesystem-safe.
No wonder XDG issues no default value, and it all disappears
into implementation code, it's a potato of above-average warmth
- makes me feel sorry i brought it up in the first place :-D
Kind regards,
T.
