Bugzilla Bug 117546

as shown by :

 * Attempting to automatically reinstall any Windows drivers
 * you might already have.
 * Driver: netbc564
mv: cannot overwrite directory `/tmp/netbc564'
netbc564 is already installed. Use -e to remove it

how to reproduce :

  `module-rebuild rebuild` twice

problems :

* mv won't succeed if another directory with the same name already exists
* if forced, it will lead to a security problem (race condition)
* assumes /tmp is available as a TMPDIR
* leaves /tmp dirty

Created an attachment (id=76051) [edit]
"obvious" patch to the problem

still problematic as :

0) not tested
1) not using a real lock and therefore has a race condition between the test
and the mv/rm
2) probably still violates the sandbox rules by using ${TMPDIR}

Well I think I fixed this by switching to using ${T} that should be used within
ebuilds. Please test ndiswrapper-1.17 and reopen if not fixed well enough. I
don't have the hardware at hand atm so I can't test.

confirmed: works like a charm, thanks
