People seem to be trying to replace HTTP with HTTPS these days.
Finally.
I used git to clone the livecd tree, as described on this page:
<
https://git.fedorahosted.org/cgit/livecd/>
It suggested three sources for cloning.
ssh://git.fedorahosted.org/git/livecd didn't work for me. Perhaps
some latency propagating my SSH key from
admin.fedoraproject.org.
http://git.fedorahosted.org/git/livecd worked. But so did the
(unlisted) https version.
==> surely the web page should suggest https, not http.
Similarly, <
https://fedoraproject.org/wiki/Livecd-iso-to-disk> had a
couple of links for things to download, both with HTTP, not HTTPS.
In the spirit of the WikiPedia motto "Be bold!", I've changed those.
