 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
 missing.
