[gentoo-portage-dev] layman: hard-coded fetching from gentoo.org and broken overlays when an 'add' is interrupted

[Amit Dor-Shifer]

Hi all. Some questions rgd layman:

   1. Seems like layman is hard-wired to contain the layman-global.txt
      list of overlays. What's the reasoning behind this? My issue
      w/this is that, lately, when gentoo.org was unreachable, this
      hard-wiring presented considerable hangs on fetch attempts.
   2. Layman refuses to overwrite an existing local overlay dir, if that
      dir already exists. I've experienced the following scenario:
         1. added an overlay and broke layman w/ctrl+C before it finished.
         2. attempted to re-execute the add action. Layman refuses,
            saying it will not overwrite the dir.
         3. attempted to remove overlay w/-d. Layman refuses, saying
            there's no such overlay.
         4. Same refusal (obviously) when attempting to sync the
            incomplete overlay.

I think layman should allow the overwrite, at least pending a (-f)orce 
flag. As far as my use-cases go, the local instance of the overlay has 
no importance: it's just a copy from some overlay repo.

Would appreciate comments,
Amit
