cdrtools-revert_sg_io_eperm_failure.patch

   1   * Add debian/patches/41_revert_sg_io_eperm_failure.dpatch:
   2     - Between 2.01+01a01 and 2.01+01a03, upstream changed the behaviour of
   3       SG_IO ioctl()s failing with EPERM; earlier releases ignored it, while
   4       the current one aborts the program. While in principle, EPERM checking
   5       is a good thing, it breaks burning for non-root users, so revert this
   6       test for now.
   7     - See also http://bugs.debian.org/374685.
