This also kills 'named' if one has it running chrooted.  The migration
process copies "/etc/namedb/*" to "/var/chroot/named/etc/namedb/" and
replaces "/etc/namedb" with a symlink.

After an update, "/etc/namedb" is overwritten back to a directory and
the subsequent 'etcupdate' reports "root.cache", "bind.keys", etc. as

As well as unbound. I was wondering why it kept getting clobbered until
I saw this thread.
