This EXPECT looks fragile for changes in UserManager/Profile implementation.
Could you make this EXPECT more robust? (e.g. instead of writing this cryptic
hash down directly in this test, get the hash from the profile or somewhere
appropriate)

[mtomasz, 2014/03/28 09:42:57]

Per offline discussion. SGTM. I'll prepare a fix.

[mtomasz, 2014/03/31 01:45:48]

Since it is not critical, how about fixing it in a separate patch? I'd like to
avoid crazy rebasing. In an upcoming patch GetMountPointPath() is moved from 
the anonymous namespace to a separate util.cc, so it would be much easier to
refactor it then, and get rid of hard-coded mount paths. WDYT?
