Seems to work for me. It gives the same answers as ofpath (packaged with yaboot 1.0.8), except for a usb floppy drive, which your script can handle but ofpath cannot. The machine is a 466Mhz G4 Powermac (Digital Audio) with an IDE harddrive and cdrom drive, and a usb floppy drive... $ ./ofpathname /dev/hda /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED] $ ./ofpathname /dev/hdc /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED] $ ./ofpathname /dev/sda /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 (for comparison) # ofpath /dev/hda /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]: # ofpath /dev/hdc /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]: # ofpath /dev/sdc ofpath: /proc/device-tree is broken. Do not use BootX to boot, use yaboot. ofpath: The yaboot HOWTO can be found here: http://www.alaska.net/~erbenson/doc So your script seems better. -- Mike Small [EMAIL PROTECTED] _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
