Hi All,
For those testing EXT4 I seem to have found an issue with anaconda where by if you specify EXT4 fstype in your kickstart file it will not install and complains that if needs another 250MB of disk space. I've tried with my kickstart set for 10G for root at ext3 and it works fine. 10,15 and 20GB with EXT4 all fail.
BTW: can't put /boot on it either.
Just a heads up for all. ;)
