If you are performating a manual partion in 9.0-RC2 bsdinstall and you delete any created partition except the most recently created one, the total remaining space will be miscalculated. Reproducable as shown below.

Workaround: if you delete a partition that is not the last partition that was created, delete all partitions created after that partition before continuing. Order does not seem to be important.

The results are similar with other hard drive sizes, with the i386 or amd64 distributions, and with either 9.0-RC2 or 9.0-RC1 (I did not go back and check install discs prior to RC1)

Reproducing the miscount:

A 114 GB drive is used for this example:

  Select Manual Partitioning

  Perform the first Create on the drive and select GPT

  Creating the first partition:  "Add Partition" "size" shows 114GB

    Change size to 4GB, set mountpoint to  /  and tab to OK
      (agree to the boot partition creation)

  Create a second partition: "Add Partition" "size" shows 110GB

    Adjust size to 10GB, set mountpoint to  /usr and tab to OK

  Create a third partition: "Add Partition" "size" shows 100GB

    Adjust size to 20GB, set mountpoint to /var, and tab to OK

  Create a 4th partition: "size" shows 80GB remaining

    Adjust size to 40GB, set mountpoint to /data,  and tab to OK.

There is 40 GB remaining on the drive. Now change the size of /var. First, delete the currently configured /var partition.

In the Partition Editor, adding up all the lines on the screen shows 54GB (plus a 64K boot) as allocated, so there should now be 60GB remaining. But the deleted /var space has not been added back into the total.

Select Create again: "Add Partition" "size" shows 40GB

   Adjust size to 30GB, set mountpoint as /var, tab to OK

A subsequent "Create" will show that 20GB is remaining, rather than the actual remaining 30GB. Selecting any size 20GB or larger for /home will give you a 20GB partition, and then an additional create will show the 10GB.
