Comment 1 for bug 355440

I'm reassigning this to ubiquity as this is not a kernel issue. I also wanted to note that I just downloaded a daily live Jaunty image http://cdimage.ubuntu.com/daily-live/20090409/ and in step 4 of the install process (Prepare disk space) I selected the "Specify paritions manually (advanced)" partition option and I see ext4 as one of the available format selections.
