[replies sent directly to me may timeout and bounce, since I'm not online as often as I should be, but I'll check the list archives] Yo How dangerous is it for me to redefine MAXPARTITIONS in src/sys/sys/disklabel.h (and diskslice.h in -stable) from 8 up to 16? NetBSD (disk type A9/169, ufs) now allows one to have up to 16 partitions in one of their DOS-partition slices, which I found useful in allowing me to view my FreeBSD partitions while running NetBSD which otherwise only sees its own (/dev/sd0a through sd0h, now through /dev/sd0p) on my multi-OS disk, by editing the additional disklabel partitions to point outside the NetBSD partition at the FreeBSD partitions (partitions, slices, whatever) FreeBSD already complains a bit about the NetBSD chunk, as it has a `d' partition covering the whole disk, plus the usual `c' partition confined as in FreeBSD to that slice. The FreeBSD kernel discards the `d' partition because it's outside of the `c' boundaries, and the same happens for the additional partitions I've added that point outside of NetBSD's `c', leaving me with just the NetBSD partitions to mount. I never use more than the traditional /dev/da0s3a through da0s3h, except within NetBSD which handles it fine. Well, I've done this with both -current and -stable, and it doesn't seem like either of them are crashing any more than usual. `disklabel' has to be rebuilt (before, the -r option worked while the ioctl failed), but in stable, mount_mfs seems hosed by my change. I'm not creating any new partitions or anything, just working with existing disks, the NetBSD part of which FreeBSD otherwise can't mount. Have I done a Bad Thing, a Really Bad Thing, an Awful Thing, or a Terrible Thing? Did I void my warranty? thanks barry bouwsma To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
