Yep, I renamed the old one, switched the repo conf to the new /var/db
location, and let emrge --sync clone a new repo directory using
git.

The 'git clone' finished OK, but the sync still failed (with a very
obtuse Python exception and stack dump) when it got to the news
processing step. After a bit of googling I found a hint that failure
happens when there is no profile selected. I ran 'eselet profile set
N'. After that, the sync completed OK.

That seems like something that should be documented somewhere...

I'll see if I can find an appropriate spot in the Wiki.
