verify.py now [after Bug 690311] ensures that we do properly remove the test root on the sdcard. This could fail for many reasons, one of them is unicode/corrupt filenames on it that adb can't figure out how to delete properly. A solution to this problem is formatting the sdcard via ADB [likely requires reboot] We could do this automatically (before buildbot starts) with verify.py when necessary, nothing in the /mnt/sdcard needs to explicitly exist before buildbot runs.

Callek: was this covered in the recent spate of verify.py improvements? Something else for Pete to tackle?

This is not covered yet, the more I think about it though I think I'd only want to do it outside of an active buildbot job. And record it, which makes me wonder if we want this in some way part of the slaveapi work. So it's still a good-to-have recovery option, but one I'm not certain where/how we actually want to insert it, and not something I want to bump priority wise above other tasks in this area atm.

Still an issue?
