No, this is Roland's configuration thing. If I'm right, you can do:
"make kernel-ide+foo+bar". This will build oskit-mach with the ide drivers
and driver foo and bar. AFAIK it's nowhere documented, I think it should be
in the readme. The problem here is that it can't find oskit/multiboot.o, when
you change OSKIT_LIBDIR to the right path it works.

No, that's the oskit code if you're going to read from a partition, it
only supports "one level of nesting" according to the documentation. With
partfs the partition code isn't in mach anymore and the problem should be
fixed.

However, the partition check is in the linux driver code, which should
always display the right results. I think this oskit-mach is linked against
the newest oskit, it should be linked against oskit 20000202. This should
be in the readme too.
