Yes, that's great, but some of the non-special cases are not that
obvious. Should I reboot or at least restart kdm after libtiff4 update?

On one host I get the feeling I don't since 'lsof 2>/dev/null | grep libtiff'
returns nothing. Then again this would suggest, that at least kde/kdm
needs to be restarted:

# apt-cache rdepends libtiff4|grep kde

So which one is it?

update-notifier seems nice, but how does it know what to do? I looked at
the code but couldn't see how it knows when to reboot and when package
upgrade is enough.
