Thanks for the information, Shane. I did:

# zfs create -o mountpoint=/usr/home/guru/zdata poudriere/mydata
# zfs create poudriere/mydata/r338641

# touch /home/guru/zdata/r338641/testfile
# find /home/guru/zdata/
/home/guru/zdata/
/home/guru/zdata/r338641
/home/guru/zdata/r338641/testfile

# mount
...
poudriere/mydata on /usr/home/guru/zdata (zfs, local, nfsv4acls)
poudriere/mydata/r338641 on /usr/home/guru/zdata/r338641 (zfs, local,
nfsv4acls)

$ ls -l /usr/home/guru/zdata/r338641
total 12994340
drwxr-xr-x  2 root  wheel        2053 Sep 25 07:04 PKGDIR.20180920
-rw-r--r--  1 root  wheel  8590762496 Sep 24 16:50 memstick.img
-r--r--r--  1 root  wheel  5806694495 Sep 24 22:47 r338641.tgz
-rw-r--r--  1 root  wheel           0 Sep 26 07:24 testfile

$ du -sh /usr/home/guru/zdata/r338641/*
7.0G    /usr/home/guru/zdata/r338641/PKGDIR.20180920
7.4G    /usr/home/guru/zdata/r338641/memstick.img
5.4G    /usr/home/guru/zdata/r338641/r338641.tgz
512B    /usr/home/guru/zdata/r338641/testfile
...

and all seems to be fine. One more question: while normal UFS
filesystem mounts are done (and stored between boots) in fstab(4), where
is the ZFS mount configuration stored?
