Yep, it's miserably slow. I use it primarily for what many people use Knoppix for - as a rescue system for dead Windows partitions. If I actually had to use it as a primary system daily I might have trouble.

Java is a pain but I believe I've used these instructions before (on a desktop install):

I did consider it.

The problem is I only know very litte about syslinux and kernel building. I was afraid I wouldn't be able to get it right without following the instructions I had which did it this way. I didn't want to spend hours more trying to figure out that one bit.

Nice to hear that you got it working.

Did you consider putting the bootloader and kernel in a separate FAT16 partition and just having the rest of the system on a normal ext3 partition? That way, you can mount the FAT16 partition at /boot and allow kernel upgrades to be done as normal.

Your approach makes me nervous because the filesystem contents are going to change dramatically at some point in the boot process. I guess it's not a major problem in practice -- filesystems get mounted pretty early on during boot -- but it's just another thing you have to be weary of when installing/configuring software.

Thank you! That was the trick. Didn't know the package name.

I'll add Multiverse and try that tonight.

Multiverse contained both 1.5 and 1.6 for me. If you're getting 1.5, you can probably also get 1.6. (Or at least, I was able to simply install them).
