Hi.

Well, I am working on a way to do that, but even though it involves a custom .upgrade file, the actual installation of individual applications can't be done using upgrade files. The problem with that is that a .upgrade either leaves a specific partition untouched, or overwrites it completely. So this whole issues has to occur in two steps:

1. create a .upgrade file with a customized kernel (to boot of hda2 instead of hda4) and an image of hda which involves a custom /sbin/init and other things.
2. install specific applications to the music partition, probably using ftp or http that is in the kernel (HiJack comes to mind)
   

If I wouldn't be extra tight on time (I sleep in my copious free time, you see), at least part one would be finished by Oct. 2001(sic!).

cu,
