Again, please perform two commits in such a case:

- the first one about APT_OPTIONS for wicd

- the second one about /proc being mounted in the chroot, since
  according to the commit log you are touching nothing else than wicd

This is a cosmetic change which should be committed separately.

Going back to the subject of this mail: why /proc must be mounted at
all?  I cannot see how this affect installation of wicd:

Is there any package that strictly require /proc for installation?
AFAIK no, thus we should not mount it at all.

Thx, bye,
