Your message dated Fri, 25 Jul 2008 14:17:02 + with message-id [EMAIL PROTECTED] and subject line Bug#473682: fixed in fakechroot 2.8-1 has caused the Debian Bug report #473682, regarding fakechroot does not properly wrap *at syscalls (openat, unlinkat, fstatat, etc) to be marked as done. This means that you claim that the problem has been dealt with. If this is not the case it is now your responsibility to reopen the Bug report if necessary, and/or fix the problem forthwith.
