apt-install, and packages adding mounts
I ran into a new problem recently. I added hotplug to the Skolelinux
CD, and because of the apt-install call in hw-detect, it was installed
by base-installer. But this package seem to mount
/target/proc/bus/usb/ at install time, and this make apt-install fail
when it tries to unmount /target/proc/.
I propose this patch to fix it, making sure all added mount points are
unmounted after the package is installed. Do you think this could
work?
