Has anyone who used the pre-test build had trouble with this switch? Since the `pretest` repository that I was using went away, I had to switch repositories, so:

    $ tlmgr option repository http://ctan.mackichan.com/

but then:

    $ tlmgr update --self
    tlmgr: Cannot load TeX Live database from http://ctan.mackichan.com/

This doesn't seem to be an issue with the specific mirror; browsing to the mirror manually shows that it is live, and changing the mirror doesn't help. `tlmgr` has been updating just fine (from the old `pretest` mirror) for months, so I don't think it's an installation issue.
