Today's updates to bind DNS -- permission denied?

This is "Solved", but I thought I'd share this in case someone else has the same problem, or if someone has some suggestions.

I run three DNS servers with bind9 on Ubuntu Server 8.04. Today I ran some updates. At the end of the update process, bind was restarted, but failed:

Oct 23 08:17:02 raptor named[18495]: starting BIND 9.4.2-P2 -u bind -t /var/lib/named

Without changing any settings, I reset two of the computers, and this problem went away on both of them. (I have not yet reset the third one)
