 I cleaned up the respective Linux descriptor I had the same idea but,
 after testing, realized that we still need it for zipping up the results.
 I just re-run the same tests on an LXC box and again preloading
 libfaketime is needed. I actually don't see a difference in this regard in
 the OS X related descriptor. Thus, I am inclined to do the same here. I
 can probably test whether that really matters later.

 Just the .zip file. Ah, end we are not exposing that one to the public.
 So, we might be fine here. Could you add that reasoning to the commit
 message to make it easier to follow our reasoning?

 \;` in `build-helpers/dzip.sh` to get rid of those timestamps without
 relying on faketime.

 That might be a good idea, generally, but I think this should be a
 different ticket. Mind to file one?

 well and should be fixed there, too, (like the sudo thing). I mean both
 KVM and LXC are using clean Debian Wheezy VMs and there should be no
 reason this descriptor fixup is needed for KVM but not for LXC.

 added to the `PATH`, except for login shells. In the case of LXC, the
 commands are run using something like `lxc-execute -- sudo -u $TUSER -i --
 [command]`, with sudo's -i option to use a login shell. In the case of
 KVM, the commands are run using `ssh $TUSER@localhost [command]` which
 doesn't use a login shell. I'm not sure how to change the ssh command to
 make it use a login shell.

 Okay, then let's leave this fix in tor-browser-bundle for now. Could you
 add a comment/hint why we need this as well?
