freebsd install on zfs

[Stellar]

I am following this guide http://www.ish.com.au/solutions/articles/freebsdzfs , but on the first part of this line :

Disklabel with options

A: 1024Mb UFS2 /
B: swap
D: rest of disk


To create D you’ll need to enter any mount point you want and then use the M option to clear it. This ensures that it will not mount or be created as a file system.

i am confused with create D, how to do it? i don't understand the meaning of "you’ll need to enter any mount point you want and then use the M option to clear it" , do i need create /tmp /var /usr ,
my system is going to be freebsd 8.1 amd64 with 3 disk,
1 x WDC Green 320 GB
2x WDC Green 500 GB

what would be good suggestion for setup zfs+ raid 1 on my system?

thanks for reading

You may want to check out mfsBSD .. it will install FreeBSD 8.1 on ZFS .. I haven't done a full server but tested it in a virtual machine and it was very straight forward. I'm waiting for an opportunity to do a full server install using this.

does this tool able to make make bootable freebsd 8.1 release + zfs 15?, i meant i need all complete package from 8.1 release iso.

It makes a base install on ZFS. But it's rather easy to packages or ports afterwards.
