Alright, I've gone ahead and installed it in VBox and I have a few things to bring up thus far.
1. A lot of elements are still "Ubuntu". The bootsplash, login manager, options in the bootloader (see 2nd image), all still specify Ubuntu. Those should be changed to JoeOS along with a custom logo for the distro.


2. I noticed some other entries in the GRUB bootloader list that shouldn't be there. I don't have any Vista installations in VirtualBox so I'm not quite sure why they are there. That needs to be cleaned out.

3. Once I logged in, I was presented with what the image below displays for the desktop. Seems to have a lot of things missing compared to the screenshots on the website.

4. Noticed some unnecessary services for a desktop. When I started the shutdown process, I saw apache2 being shutdown. That I know of, this isn't included on stock Ubuntu for desktop at all.

Do you know if he's doing this on a clean system? I wonder if he could create this distribution using VirtualBox so that it's not tainted with files on a production machine.
I do look forward to playing with future versions of JoeOS in the future as it matures.
