YUMI multiboot usb: No init found. Try passing init= bootarg.

[Amedee Van Gasse]

I made a multiboot usb with YUMI (Your USB Multiboot Installer, from
http://www.pendrivelinux.com). It seems to be working for most of the 42
distributions that I installed on my 16 GiB usb stick, except for all the
Ubuntus and Ubuntu-based distros like Mint.

The boot process fails with the following error:
No init found. Try passing init= bootarg.
and then drops to a root shell.

This is the boot cfg (grub) for Ubuntu Netbook 10.10:

Compare this with the boot cfg for Debian:
http://paste.ubuntu.com/581150/

Any ideas what's wrong?
If this can be solved, then I will submit the solution to
pendrivelinux.com so that they can fix the problem.

Kind regards,
Amedee
