No, grub handles this fine. The grub device.map just tells the grub-install script which device in /dev to open and what BIOS drive to treat it as where (hd0) = 0x80, (hd1) = 0x81, etc. If the first scsi disk is mapped to /dev/sdb, but it is in fact the boot disk, then the above device line works fine as it has grub write the various boot stage binary bits to /dev/sdb and causes the binary bits to ask for bios device 0x80 when actually used to boot the machine. > > > > I'm adding Doug to cc: in case he knows a case where LVM2 encodes > > device minors into an on-disk format. > > > > Yours, > > -- Pete > > > > -- > > fedora-devel-list mailing list > > fedora-devel-list@xxxxxxxxxx > > https://www.redhat.com/mailman/listinfo/fedora-devel-list > -- Doug Ledford <dledford@xxxxxxxxxx> GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband
