Can DFly mount ext4?

[Pierre Abbat <phma@xxxxxxxxxxxxx>]

A friend gave me an Ubuntu laptop which I proceeded to install a few programs 
on and then hose. It came with a user "a" which I decided to change 
to "phma". I renamed the home directory, edited /etc/passwd and /etc/group, 
and rebooted. I had forgotten to edit /etc/shadow, so I can't log in. It's 
set up to show "Ubuntu" and four dots instead of a GRUB prompt. I tried 
mounting it in the USB enclosure on my Linux box; it said "unsupported 
features", which a bit of googling tells me means it's an ext4 filesystem. I 
try mounting it on DragonFly as ext2fs and get "invalid argument". Is there a 
way to mount ext4fs?
