You saved me the trouble of typing all this up. :)

I would add that it isn't necessary for you to define a loop0 *and* a loop1 in grub, as grub only needs to know about your new boot.disk in order to boot. The "loop=" kernel parameter referencing root.disk is unrelated, and has nothing to do with grub. Rest assured the kernel will find the root.disk when the time comes. Hence simply defining loop0 to be /ubuntu/disks/boot.disk is adequate. Which also means that /boot/grub/grub.cfg requires absolutely no changes. :)

The missing piece to your (my) instructions is how to make grub-install now do the correct thing to /host/wubildr (on C:\) in order for the system to boot as normal to the grub menu. As I mentioned previously, it requires a rather simple change to /usr/share/lupin-support/grub-mkimage, which I've attached as a unified-diff patch. After creating the separate boot.disk and applying my patch, you can simply run e.g. "grub-install hd0" and wubildr will now properly update to boot your boot.disk, and all will be right in the world. heheh.

By the way, grub-install leaves all the files behind in /boot/grub that it uses to generate wubildr, which it REALLY should clean up afterwards. They're harmless, but it's messy.

got a grub> prompt and ran these commands:

root (hd0,1)

loopback loop0 /ubuntu/disks/root.disk

loopback loop1 /ubunut/disks/boot.disk

root (loop1)

# note: get the kernel and ramdisk from the boot.disk filesystem

linux /vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro

initrd /initrd.img-2.6.31-14-generic

Sun's Java JDK

You can install the Sun Microsystems JDK either by installing from the Ubuntu repositories or via a more manual process of downloading and creating your own packages

Once you have Eclipse up and running the WTP can be installed using Eclipse's own "Software Updates" mechanism: Go to "Help -> Software Updates -> Find and Install", select the "Callisto Discovery Site" and later the "Web and J2EE development" plugin group. Click "Select required" to automatically select all the dependencies.

You might want to install to "/usr/local/lib/eclipse" to make the plugins available for other users.

Ubuntu 9.10 - Karmic Koala

Eclipse 3.5.1 is available in Synaptic Package Manager.

Eclipse and Sun Java

To install the Sun Microsystems JDK, install the sun-java6-jdk package from the multiverse repository.

By default, the Eclipse which is packaged with Ubuntu runs with the GCJ JVM and not the JVM supplied by Sun Microsystems even if you have installed the Sun Microsystems version.
