Shane - ZFS Deletion

G'day Guys,

In episode 139 you had a couple of questions I thought I would respond to.

For John - Destroying zfs datasets

While Allen's suggestion of keeping everything under a parent dataset
is a good idea, you may not always want to destroy every child set.

For an example take the poudriere layout, say I have
/usr/local/poudriere/jails/101amd64
/usr/local/poudriere/jails/101i386
/usr/local/poudriere/jails/102amd64
/usr/local/poudriere/jails/102i386
/usr/local/poudriere/jails/103amd64
/usr/local/poudriere/jails/103i386

and I want to get rid of all the 10.1 and 10.2 filesystems - destroying
poudriere/jails will also destroy the 10.3 filesystems I want to keep.

To handle this situation I would use -

zfs list -o name | awk '/poudriere/ && (/101/ || /102/)' | xargs -L1 zfs destroy -R

For Thomas - question 2 - missing port messages

You can get the message of an installed port with
pkg info -D security/tor
or
pkg info -D tor-0.2.7.6_1
Which can be expanded to go through all installed ports messages with

pkg info -qa | xargs pkg info -D | more
