>Yeah, reassign this bug to 'mount' and 'rm'.

First of all, you should not close a bug without a proper explanation.

mount and rm does exactly what they are meant to do (and what is 
documented). This is not true for your package.

In fact, this bug is easily fixable:
- In most cases, `umount -a` called inside chroot does unmount 
everything that should be unmounted.
- If it does not (i.e. if /proc/mounts contents changed during a build), 
pbuilder should refrain from rm-Rf-ing the chroot.
