#1 RFE: create user data set if it doesnt exist

[Anil Gulecha]

devzone_create should create user data set if it doesnt exist.. currently it has to be done manually.

It fails with
"could not verify zfs dataset tank/users/mlo: dataset does not exist"
or
"could not verify zfs dataset tank/users/mlo: mountpoint cannot be inherited"

Solution
---
zfs create tank/users/username
zfs set mountpoint=none tank/users/username

and then devzone_create works.
