This is a followup to <https://git-annex.branchable.com/forum/basic_usage_questions/> – I'm actually testing the "two repos at same URL" situation now, with git-annex 6.20160211 and 6.20160221.

So I have a git-annex repo on two hosts at `rain:~/Attic/Software`, `frost:~/Attic/Software`, and a third clone at `/mnt/portable_HD/Attic/Software`. This means that the repo on the portable HD has two remotes with identical paths, but corresponding to different repositories:

    rain    /home/grawity/Attic/Software
    frost   /home/grawity/Attic/Software

[I was told earlier](/forum/basic_usage_questions) that this configuration would work fine and git-annex would not get confused. However, that doesn't seem to be the case (unless I misunderstood what it considers to be the "right thing"?) I see that whenever I run a command like `git annex info` on the portable\_HD repo, it overrides `remote.{rain,frost}.annex-uuid` with whatever UUID it sees right now – resulting in `git annex info` output such as:

    ┌ frost /run/media/grawity/vol4_grimoire/Attic/Software master
    ┘ git config -l | grep annex-uuid
    remote.origin.annex-uuid=0ebc2083-f95e-4637-bd3e-09db8471daf3

Notice how the `[rain]` remote tag now shows up next to the wrong remote. Among other things, **this means I cannot use `git annex find --in frost --not --in rain`** and similar commands (unless I specify all the UUIDs by hand). And even though I trust git-annex to not lose any data, this behavior is a bit confusing.

Is it possible that git-annex could detect such situations and avoid updating an UUID if it's _already attached_ to another remote?
