To: Debian Bug Tracking System <[email protected]> Package: grub-common Version: 2.02~beta2-22+deb8u1 Severity: normal Tags: patch The script /etc/grub.d/30_os-prober does not provide the correct device name for booting the Hurd, e.g. when installed with crosshurd. The bug also applies to the grub version currently in sid. The patch changes provided device names from, e.g.: (hostdisk//dev/sda,msdos2) to: hd0s2 This is the patch that solved the problem in my case, and may be correct: ----------------------------------------------------------------------------- --- 30_os-prober 2016-02-05 18:30:35.000000000 +0100 +++ 30_os-prober-2 2016-05-25 17:13:17.518318125 +0200 @@ -332,13 +332,14 @@ prepare_grub_to_access_device ${DEVICE} | grub_add_tab grub_device="`${grub_probe} --device ${DEVICE} --target=drive`" mach_device="`echo "${grub_device}" | sed -e 's/(\(hd.*\),msdos\(.*\))/\1s\2/'`" + hurd_device=`${grub_probe} --device ${DEVICE} --target=compatibility_hint | sed 's/,msdos/s/'` grub_fs="`${grub_probe} --device ${DEVICE} --target=fs`" case "${grub_fs}" in *fs) hurd_fs="${grub_fs}" ;; *) hurd_fs="${grub_fs}fs" ;; esac cat << EOF - multiboot /boot/gnumach.gz root=device:${mach_device} + multiboot /boot/gnumach.gz root=device:${hurd_device} module /hurd/${hurd_fs}.static ${hurd_fs} --readonly \\ --multiboot-command-line='\${kernel-command-line}' \\ --host-priv-port='\${host-port}' \\ -----------------------------------------------------------------------------
