Agreed it seems there is no urgency, now.

Unfortunately it's not that easy to change. See Compatibility with
CC-BY-SA<http://en.wikipedia.org/wiki/GNU_Free_Documentation_License#Compatibility_with_CC-BY-SA>on
Wikipedia. There is one-way compatibility, from GFDL 1.3, or 1.2 with
the
"or any later version" declaration, to CC-BY-SA 3.0. (And that is subject to
a time limit of the end of July, 2009 (2 days away).

However, PCMan pointed out that GFDL 1.2 (used by the LXDE wiki) does not
automatically include an "or any later version" option. I was not aware of
this. So, if I understand correctly, to change to either GFDL 1.3 or to
CC-BY-SA 3.0 or any other license would require the approval of all
contributors

Unfortunately that can't be done. So, if the wiki remains GNU FDL, it will
be unable to share in either direction with most wikis and other sites.

Still, sites have changed license before. Wikitravel is in the process now,
and this can provide an example of how to do it. (Their site notice
currently states *Discussion is underway about a potential site-wide License
upgrade <http://wikitravel.org/shared/License_upgrade>*.) I would recommend
doing this, to ensure compatibility with other wikis. The sooner it is
started, the less painful it will be, and the less work there will be to
find and remove the edits of editors who do not give their approval to the
change.

Wikipedia's dual license is probably the best option - so all content would
be CC-BY-SA 3.0 *and *GFDL (unless otherwise marked) but if CC-BY-SA-only
content is added in from another souce, then the page becomes CC-BY-SA-only,
and it is up to reusers to check this before using as GFDL. (If there is no
attribution on the page to a CC-BY-SA site, then it should mean there is no
problem, but of course someone may have failed to attribute properly, so we
must watch out for copyright/license violations, as usual.)

There are some issues around what is a Debian-approved (DFSG) license for
images, which I don't fully understand - these things will need to be
decided first.
