My favorite is Knoppix 6.2.
It does do ext4.

I have been using Fedora 11, x86_64 for about a month now. It just occurred
to me to check what fileystem Fedora installed. I recall during the
installation I told it to use the entire hard disk and just clicked OK on
the defaults. Turns out that it created a 200 MB ext3 boot partition and a
logical volume of 297 GB which contains an ext4 root partition and a small
swap partition.

I have several rescue CDs, from Knoppix to smaller command line only disks.
Guess what? They're all too old to be able to fix an ext4 filesystem. My
very, very dim understanding is that older systems (with ext3) can
read/write to an ext4 filesystem, but the older e2fsck won't work. I may
well be wrong about the read/write - that is, I may have it backwards.

Fedora started using ext4 with Fedora 10. Ubuntu made it optional with
Jaunty, and Karmic uses it exclusively.

It's Clinic Eve, so I am downloading some more recent rescue CDs. At the
Clinic tomorrow I will boot them and see which ones can deal with my ext4
root partition.
