Yes: <http://www.gnu.org/software/hurd/open_issues/blkrrpart_ioctl.html> Of course, this problem will go away / shift from the kernel into user-space processes as soon as we have disk I/O completely handled in user space. Which, by the way, should theoretically already be possible (mostly -- at least for handling partitions), as Neal (I think) has added a GNU parted backend to libstore, years ago. That's what I think, at least. :-) More verbosely: you can use storeio (libstore) to access disk partitions on a Mach hd* device, instead of using storeio (libstore) directly on the Mach-provided hd*s* partitions. I don't know whether / how that libstore backend works, etc. Someone could explore and document that. We will need it as soon as we switch from the Mach disk device handling to something more modern (DDE). Next topic: DDE. Zheng, I'll work on your Makefile issues *now*. Really *now*. Finally. Sorry for the delay. Regards, Thomas
