I have tested the echo -e "(hd0)\tY" > X/grub/device.map grub-install --boot-directory=X '(hd0)' approach with all combinations of * Git HEAD, Debian wheezy (1.99), Debian jessie (2.02~beta2) * a loop device, an LVM volume by now. Of those * the only one that fails is loop device on Debian wheezy [1] (I welcome a workaround for that, too!) and * the only one requiring manual symlink resolution (e.g. passing /dev/dm-9 rather than /dev/mapper/vg-lv) is again Debian wheezy. So that approach should allow me to patch future releases grml-debootstrap for jessie, stretch and sid. Nevertheless, let's get good old grub-install --boot-directory=... /dev/... fixed, please. It did work previously. How do we proceed? Best, Sebastian PS: I have not tested any from-within-chroot cases yet. Those have given different results to some extent in the past, at least. [1] In the the shell: # grub-install --boot-directory=/mnt/loop-root/boot '(hd0)' ; echo $? /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/loop0p1. Check your device.map. Auto-detection of a filesystem of /dev/mapper/loop0p1 failed. Try with --recheck. If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/mnt/loop-root/boot/grub/device.map" --target=fs -v /mnt/loop-root/boot/grub" to <bug-g...@gnu.org> 1 # mount | fgrep /mnt/loop-root /dev/mapper/loop0p1 on /mnt/loop-root type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered) # cat /mnt/loop-root/boot/grub/device.map (hd0) /dev/loop0 _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
