Subject:   Stupid question regarding ZFS and `df -h` output

I installed FreeBSD using steps like "Next -> Next -> ZFS -> use entire
disk and don't bother me with stupid questions -> Next"

I have 128 Gb hard drive:

ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: Serial Number 82GS10GGT2GY
ada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes)
ada0: Command Queueing enabled
ada0: 122104MB (250069680 512 byte sectors)

And here is `df -h` output:

Filesystem            Size    Used   Avail Capacity  Mounted on
zroot/ROOT/default     95G     21G     74G    22%    /
devfs                 1.0K    1.0K      0B   100%    /dev

zroot/var/log          74G    360K     74G     0%    /var/log
zroot/var/mail         74G    188K     74G     0%    /var/mail
zroot/var/tmp          74G    136K     74G     0%    /var/tmp
zroot                  74G     96K     74G     0%    /zroot

How exactly should I read this to get result "all 128 GB are used"?
