- Force Package[bind] to be installed before moving /etc/bind into the
$chroot_dir
- Fix recursive permissions for /var/bind9/chroot/** directories (so
that user bind can cross those directories if they belong to root)
- RHEL chroot code has been moved into a bind::chroot::package class
- Debian family (and probably other families) can use the
`bind::chroot::manual` class to enable chroot for bind using the method
described here: https://wiki.debian.org/Bind9#Bind_Chroot
