Currently, our "normal" builds happen in /builds/slave/ and our scratchbox builds happen in /scratchbox/users/cltbld/home/cltbld/build/. This is fine for the most part, as a buildbot job can start in /builds/slave/___ and then run commands in some other directory. However, clobberer expects to find build dirs in /builds/slave/. I believe we already bind mount /builds/slave to /scratchbox/users/cltbld/builds/slave; if we build here we'll get clobbering for free. However, a) we have to change a bunch of paths and make sure they work, and b) the fact that this isn't in cltbld's home directory in scratchbox may present some interesting scratchbox command problems (the latter may be solved by bind mounting it to /scratchbox/users/cltbld/home/cltbld/something if it turns out to be an issue).

John: Aki says you've already done some work on this. What's been done/tried and how much work would remain?

like bug 557260, marking as WONTFIX

Well, as we are reopening bug 557260 to do that work, this bug will be fixed by that bug and is a duplicate
