Hello all,

While testing this patch series further in a more complex environment, I 
noticed some build errors that I did not get with pristine Isar builds.
The build logs show mkstemp being called in the buildchroot'ed environment 
and failing to find /tmp. Gentoo's guide was also bind mounting /tmp
I am however unclear on why this shows up with this particular change.
