To reproduce install a linux distro with on an xfs with either a /home or / mountpoint then download the latest ubuntu-mate iso or antoher flavor and select something else in the partitioning. The installs I have on an ext4 partition are shown but the installs on an xfs partition shows unkown free. from selecting install at the menu if I press control alt t in ubuntu mate it brings up a terminal and I can see the used space on the xfs partitions by runing sudo gparted.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected the free space column to calculate xfs partition used space seeing as it is an old and mature filesystem. Instead I get unkwon as the size but the iso can see the used space in gparted. I can still install but seeing free space would be nice.
