- Make an Ext3 partition on the USB stick (I used the USB stick with
my bootloader partition, just added a new partition after the
bootloader)
- Copy the contents of a Mythbuntu live CD to the Ext3 partition. I
did a straight file copy, nothing special.
- Boot the ATV from the USB stick
- Mount the Ext3 partition
- Use kexec to start the Mythbuntu kernel
- Install Mythbuntu onto the internal hard drive
For Mythbuntu the mount and kexec commands were:
--> mount /dev/sdb3 /tmp
--> kexec --load /tmp/casper/vmlinuz --initrd=/tmp/casper/initrd.gz --
command-line="boot=casper initrd=/casper/initrd.gz nosplash vesa
video=vesafb"
--> kexec -e
I also see the "mount proc/mounts: No such file or directory" when
booting from the hard drive after installing. But the bootloader still
finds and boots the kernel.
