That's a good thing to ask, it seems like a more obvious place to start. Currently (hd0) is preferred unless we're able to detect that it is install media. That's the problem currently. *Only* if we'd detected it as install media, we would fall back to: > 575 bootfs=$(findfs /boot) > 576 [ "$bootfs" ] || bootfs="$(findfs /)" (That does a grub probe of /boot or / in the target, or otherwise whatever seems mounted on /target/boot or /target) But wouldn't that be a better default_bootdev, for any grub-legacy/pc/sparc/ieee1275 install? Could we try to determine default_bootdev that way to begin with? It would just require a shuffle round of the code that is already there. I'm picturing something like: > case $ARCH:$grub_package in > *:grub|*:grub-pc|sparc:grub-ieee1275) > # For GRUB installs this should be a better starting point > bootfs=$(findfs /boot) > [ "$bootfs" ] || bootfs="$(findfs /)" > default_bootdev=$(device_to_disk "$bootfs") > ;; > *) > # This was the original default > default_bootdev_os="$($chroot $ROOT grub-mkdevicemap --no-floppy -m > - | head -n1 | cut -f2)" > if [ "$default_bootdev_os" ]; then > default_bootdev="$($chroot $ROOT readlink -f > "$default_bootdev_os")" > else > default_bootdev="(hd0)" > fi > ;; > esac <then the usual sanity checks as before; prompt if unsure> Regards, -- Steven Chamberlain ste...@pyro.eu.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
