Hmm, I just checked the link and like the last time I tried it, it
doesn't work.

~ $ curl
"http://dev.odroid.com/projects/4412boot/wiki/FrontPage?action=download&value=boot.tar.gz"
curl: (52) Empty reply from server

So either I'm just unlucky, or the server is highly unstable, or maybe
routing problems cause it only to be available for certain regions.

Since I've heard the complaint (that the link is not working) from
several people, I don't think it's a good idea to leave it there. GitHub
provides a much more stable service, so I would prefer to remove the
'wonky' link.

With best wishes,
Tobias
