zfsなpool(tank)を/usr/homeにする†

ada0 に、完結した？システムが出来ているので、残りの ada1 ada2 ada3 上にpoolを作って　/usr/home　にしましょう

現状†

g7# df -h
Filesystem          Size    Used   Avail Capacity  Mounted on
zfspool/root        220G    6.5G    213G     3%    /
devfs               1.0k    1.0k      0B   100%    /dev
tank                456G     40k    456G     0%    /tank
zfspool/root/tmp    213G     62k    213G     0%    /tmp
zfspool/root/var    214G    222M    213G     0%    /var
devfs               1.0k    1.0k      0B   100%    /var/named/dev
