I understand the Ubuntu is running in a chroot environment - i.e. 'on top of' WebOS

I have my TouchPad now and I'm ready to play, but I do not want to brick it (yet). What I would like to do is keep WebOS as the primay OS, but be able to load a seperate (stock standard) Linux kernel and initrd. ljesterl has indicated he is running U-Boot, but I think he needs to have the TouchPad plugged into has computer to do so. I suppose it is not critical right now that dual-boot is done without the TouchPad plugged in, but WebOS should boot cleanly from power-up normally.

Ulitimately, I want to dual-boot (without having to plug in) between WebOS and a vanilla Linux kernel + LFS (Linux from Scratch) OS (and possibly triple-boot into Android)

I don't suppose anybody has played with using resizefat to make space available for the ubuntu chroot environment? I'm too lazy to use meta-doctor because it means backing everything up and then putting it back on, and I'm afraid of manually messing with the partition table due to brick potential.

I don't know of any tutorials but if you know about recoveries or boot managers you can mod uboot to allow dual boots without a pc
the only reason he is plugged in is to either issue commands or for that new BS safety feature that requires a charge to do anything

That is what I'm talking about :)

I finally have my TouchPad and downloaded NovaTerm/NovaCom and the SDK last night, so I now have root access and access to bootie - Now I just need to find out what U-Boot patches are needed and how to run it - I am thinking that:
- U-Boot can be loaded into memory and executed from Bootie
- U-Boot can load and execute WebOS
- U-Boot could be copied onto the TouchPad iNAND and the Bootie environment changed to load U-Boot instead of WebOS
- U-Boot could monitor a hardware input (say the 'Volume Down' button) and load an alternate OS instead of WebOS

This will be my focus - Hopefully one day I can then get rid of Bootie entirely and have U-Boot as the main bootloader
