Maybe apt-cache policy is broken on Mike's system? It takes about fifteen seconds for apt-cache to run on a system that hasn't previously accessed those files. That's a significant fraction of the overall reboot time. Much longer when the cached files need to be rebuild and again much longer with multiple architectures. Rebuilding the caches for an apt-cache policy run on kfreebsd-amd64 (with kfreebsd-i386, amd64 and i386 archs added) takes forever.

If you run apt-cache as non-root, the latter won't get updated so the long delay will happen every single time.

My /etc/init.d/bind9 has: DISTRO=$(lsb_release -is 2/dev/null || echo Debian) lsb_release seems to call apt-cache policy. On one hand, the value of $DISTRO doesn't seem to be used anywhere.

Mike Bird wrote: Seen in Lenny. Is it really necessary to run apt-cache in order to shut down BIND? The Lenny package's /etc/init.d/bind9 script calls 'lsb_release -is' to determine the distribution and if the 'lsb-release' package is installed then the lsb_release script calls 'apt-cache policy'. The result of which was not used. I believe you could comment out that line without any ill effects although I didn't test it. Or alternatively you could remove the 'lsb-release' package. The current Sid version of bind9's /etc/init.d/bind9 script does not call 'lsb_release' and therefore this issue seems to have been addressed in the latest Squeeze. Bob P.S.
