Bug#728057: adt-virt-schroot: set incorrect TMPDIR permissions

Severity: normal

Hi,

I ran into an issue that took me quite some time to track down. It turns
out that adt-run sets a TMPDIR to a directory with insufficient
permissions.

From within a running test:

TMPDIR=/tmp/adt-run.WQzHYl/dsc0t-testsuite-testtmp/tmpdir

4 drwxrwxrwt  4 root root 4096 Oct 27 21:32 /tmp/adt-run.WQzHYl/dsc0t-testsuite-testtmp/tmpdir/
4 drwx------  4 root root 4096 Oct 27 21:32 /tmp/adt-run.WQzHYl/dsc0t-testsuite-testtmp/
4 drwxr-xr-x  6 root root 4096 Oct 27 21:32 /tmp/adt-run.WQzHYl/
4 drwxrwxrwt 10 root root 4096 Oct 27 21:31 /tmp/

The permissions of /tmp/adt-run.WQzHYl/dsc0t-testsuite-testtmp are
wrong. The test script runs some parts of the tests as a non-privileged
user that cannot access files under TMPDIR.

Setting a more liberal umask before running atd-run fixes the issue. The
attached patch also fixes the issue but I haven't checked whether other
directories are created with the correct permissions.

Thanks,
