I don't really understand why you ask a FreeBSD group about it; it's a Linux issue. FWIW, about the only area where you're liable to run into difficulties is in the disk label handling round line 300, which is pretty peripheral to the function: it's just there as one way of finding out the size of the partition. You'll need in-depth Linux information to even find out if Linux has an equivalent function. If you have any other problems, send me the compiler output and I'll guess at what it might be.
