Bug Description
Binary package hint: mountall
In attempting to keep the archive clear of executable stacks, I'd like to rework mountall to not use nested functions.

This bug was fixed in the package mountall - 0.1.8
---------------
mountall (0.1.8) karmic; urgency=low
[ Scott James Remnant ]
* Further work on the fix from the previous version where the root
filesystem would always be considered "local", retain that from the
POV of the {virtual,
the root straight away when it's virtual since there's no device to
wait until it's ready. LP: #431204.
* If a remote filesystem is already mounted and doesn't need a remount,
don't wait for a network device to come up. LP: #430348.
* Ignore single and double quotes in fstab device specifications, since
mount -a used to. LP: #431064.
* Never write mtab when mounting a mount with showthroughs (ie. /var)
and instead update mtab once we've moved it into place
later. LP: #434172.
[ Kees Cook ]
* src/mountall.c: rework nftw hooks to use a global for argument passing
instead of using nested functions and the resulting trampolines that
cause an executable stack. LP: #434813.
* debian/rules: revert powerpc exception, since the cause is fixed by
removing the nested functions.
