Comment 4 for bug 515706

To be clear, in postinst I have:
start procps

and in postrm, on purge, I have:
start procps

This means that the /etc/sysctl.d tree gets applied after install (that's probably ok) and reapplied after purge which is a problem in two ways:
- settings are still applied while the package isn't purged (but only removed); I think that's acceptable, even if not perfect
- settings which were overriden by qemu-kvm-extra-static's /etc/sysctl.d/ config will only be reset if another file in /etc/sysctl.d also sets them; this is true for mmap minaddr for instance, but perhaps not for other settings such as vm.vdso_enabled on i386.
