I know how to make a live USB but I was curious about installing to my usb stick and make that a live usb w/ an actual installation on there.

I know how to make a live USB but I was curious about installing to my usb stick and make that a live usb w/ an actual installation on there. Sure, it is possible.

Its almost the same as a standard install.
Be sure to build USB and USB storage support into the kernel, as you will need them to mount root 2. Add rootdelay= to the kernel line in grub.conf 3. Build a kernel that can boot without an initrd Values of from 7 to 30 have been found to work. Normally, root is mounted before the USB system is initialised. Thats a bit of a problem with root on USB.
This delay allows the USB system to settle before the kernel goes looking for root.

Basically, if you configure a driver/symbol/whatever in the kernel as a module, instead of a built in, it is stored on your root partition. In order for this module to be accessible, the partition must first be mounted.
If that module is one needed for mounting the root partition, you're hosed!
