Re: strangest things after upgrade from 8 to 9

The Debian upgrade will run ldconfig and the Debian maintainers are not
likely to get it wrong.

I'll concede that it might be possible to bugger up your system in such
a way as to make an upgrade fail by installing a sufficiently broken
package in /usr/local but it's going to be a rare corner case.
