Upgrade to ext4, how?

[Martin Sourada]

Ok, here's more info on what I did and what went wrong:

1. I changed my /etc/fstab file to look thus: (see attachment).

2. I ran mkinitrd initrd-2.6.25-0.195.rc8.git1.fc9.i686.img
2.6.25-0.195.rc8.git1.fc9.i686

3. I rebooted the computer to 2.6.25-0.195.rc8.git1.fc9.i686 kernel

4. After a while these messages appeared (starting from first
suspicious):

EXT4-fs: dm0: not marked OK to use with test code.
mount: error mounting /dev/root on /sysroot as ext4dev: Invalid argument
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Mount failed for selinuxfs on /selinux: No such file or directory
switchroot: mount failed: No such file or directory

Perhaps I am missing some step that needs to be done first? Any thoughts
what's wrong there?

Thanks,
Martin
