Follow-up Comment #4, bug #36640 (project grub):
Vladimir,
thanks for coming up with a patch so quickly! As you pasted the patch inline,
copy-paste produced a malformed patch ..
# patch -p 0 < patch
patching file util/getroot.c
patch: **** malformed patch at line 4: ptr = ret + sizeof ("/dev/disk") +
rdisk - 1;
.. with whitespace broken and even some '*'s missing.
I believed I was able to restore the patch correctly, see [1] for my result to
be sure.
Fortunately, the patch seems to work well. I confirm all(?) possible
combinations working:
# for d in /dev/loop7 /dev/GRUB_BOOT_TEST_DISK ; do
for m in normal-device.map symlink-device.map
both-a-b-device.map both-b-a-device.map '' ; do
printf "[%s][%s] -> " "$d" "$m";
./grub-probe --device-map="$m" --target=drive
--device "$d" ;
done ;
done
[/dev/loop7][normal-device.map] -> (hd0)
[/dev/loop7][symlink-device.map] -> (hd0)
[/dev/loop7][both-a-b-device.map] -> (hd0)
[/dev/loop7][both-b-a-device.map] -> (hd0)
[/dev/loop7][] -> (hostdisk//dev/loop7)
[/dev/GRUB_BOOT_TEST_DISK][normal-device.map] -> (hd0)
[/dev/GRUB_BOOT_TEST_DISK][symlink-device.map] -> (hd0)
[/dev/GRUB_BOOT_TEST_DISK][both-a-b-device.map] -> (hd0)
[/dev/GRUB_BOOT_TEST_DISK][both-b-a-device.map] -> (hd0)
[/dev/GRUB_BOOT_TEST_DISK][] -> (hostdisk//dev/loop7)
Best,
Sebastian
