[izpack-users] Available space question

[Per Newgro]

Hi, 

i use linux. This are my disk parts:
filesystem          1K-Blocks   Used Available Used% Mounted at
/dev/hda2              9288792   4311192   4505692  49% /
udev                    387960        80    387880   1% /dev
/dev/hda5             35095848   9746916  23566124  30% /home
/dev/hda4             32258516  20620804  11637712  64% /windows/C

If i install my application in /home/myuser/opt i expected that the available 
space is 9,7GB but it is 4,3GB. Is that a problem of izpack or of my disk 
parts :-).

Cheers
