stress that _yet_:
this will happen with any and all configuration stuff standarized by
yes that's only the menu at the moment (I think). but more stuff will be
added over t ime (e.g. the shared keyboard shortcuts being worked on ,
will undoubtfully have a global set of defaults for things like save,

which set(s) of configuration to use is ultimately admin decision
-> it's not something you can standarize (beyond use XDG*_DIRS to set it up,
it'll default to that, and should be interpreted like this, which we
-> having the different desktops provide their view on good defaults only

default situation on a given distro is the distro's choice (I don't think

yep, so that's where I'd expect the upstream desktop to place it by default,
I'd also expect them to have a configure option to change that default, and
for distro's to use that option when packaging.
I also fully expect most distro's to then create their own set of defaults
partly or wholly ignoring the upstream choices, and I expect that's
configuration set that will end up in /etc/xdg not the upstream desktop
If the distro just installs all configuration sets in the same place, then
IMO that distro is broken (setting up lots of (Free) Software so it'll work
together coherently is the whole point of having distros no?)

putting it in the desktop startup script(s) is bad:
- if you have people using X different desktops, you then need to manage it
in X different startup scripts
- you might not use a desktop environment (and thus it's startup script),
but only some apps of each desktop-environment -> the desktop startup
script wouldn't be run, but you'd still need the environment variables to
be setup correctly
desktop-profiles puts it in an Xsession.d script (script that get's sourced
on any X-startup in Debian, not sure if that carries to other distros)

you don't need to change the entire prefix, just which dir to put the
freedesktop-standarized stuff in (which should be independend from the

the contents of XDG_CONFIG_DIRS is a system-specific-setting not a
(Actually in larger setups it's more likely to be a group-specific setting,
i.e. use configuration A if user is a member of group students, use
configuration B if user is a member of group teachers, ...)
using different XDG_CONFIG_DIRS for the different desktops (on the same
system), completely defeats the reason for standarizing stuff in the first

Well, you'd now be able to install both desktops on the system without using
configure-options when compiling them, beyond that you haven't gained
anything though. When installing multiple desktops you (or the distro)
still needs to set up XDG_CONFIG_DIRS to use the view on defaults provided
by one of the available desktops by default.
