Ah...  One of my major bugaboos.  I keep pissing in peoples corn flakes
over making the template generic.  This is really an issue for lxc-devel
aot lxc-users but that's another matter.

Daniel authored it and I've made a number of modifications /
contributions.  What version of lxc-tools are you running?

Oh?  That's an area where I've already had my fingers in.  Release ver,
please?  Things in git are likely to be working better there.

That does NOT sound like something related to inserting anything in the
path.  That's related to an SSL cert not verifying to the FQDN to the
originating site.  That has nothing to do with the longer URL past the
FQDN.  Cut and paste the errors.

Within distro, F{X} to F{Y} I have verified it working from F14 through
F19 to F12 through F18.  From Ubuntu to Fedora, it should be working.
It's not perfect and I'm not at all certain it would work from OpenSUSE
or Arch or several others (but, it if doesn't, it never did) but that's
a problem I keep bitching about and I'm not certain it has an answer.
At least OpenSUSE has rpm and Ubuntu has febboot and yum support.  But
that's not the answer to the distro-agnostic templates.

It certainly works on Ubuntu and Fedora.  You'll have to provide a few
more details there since I don't know any reason why it shouldn't honor
a "-t fedora -- -R 18" option.  what error do you get???
