using zfs for poudriere

[Matthias Apitz]

Hello,

I do use for some years a zpool for poudriere(8) ports building. I just
created it with:

# grep zfs /etc/rc.conf
zfs_enable="YES"


# zpool create poudriere /dev/da1

# zpool list
NAME        SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
poudriere   278G  4.09G   274G        -         -    13%     1%  1.00x  ONLINE  -

But I have to say, that I really don't know how poudriere makes use of
it because I have never worked, a part of this poudriere usage, with
ZFS.

Can someone pleas explain me *what* do I see with the commands below?
For me the mountpoints (when I use 'ls') always look somewhat empty, but
when poudriere is running (see below) it creates a lot of things there.

And one additional question: Can I store some own data below /poudriere
(because I'm running out of space in my UFS /dev/da0 partition) without
disturbing poudriere in its work?

Thanks in advance for any enlightenments.
