[winswitch] /run/xpra directory permissions

[shanew at shanew.net]

Do you have the file /usr/lib/tmpfiles.d/xpra.conf on your gentoo
installation?  This should cause gentoo to create the /run/xpra
directory with the appropriate permission at boot time (since /run is
a tmpfs thing these days).

Note though that users will need to be in the xpra group for this to
work.  If you don't want that group restriction, you could edit that
file so that the permissions get set to 777 (or add an over-riding
entry to /etc/tmpfiles.d, since the package installed one will likely
get over-written when you update).
