Bug#494589: grub-setup fails with "error message = file not found"

[Edward Allcutt]

I initially reported this as Debian bug #494589 [0]

Felix Zielcke asked me to forward this report to this mailing list.

Reproduced with latest upstream SVN (rebuilt r1802 today).

Failing command:
grub-setup -vv --directory=/boot/grub --device-map=/boot/grub/device.map 
'(hd0)' >grub-setup.log 2>&1

grub-setup.log is available at [1]

/boot/grub/core.img exists and was created normally by grub-install. I 
looked at the parameters passed to grub-mkimage and it was using the 
correct modules (ext2 gpt biosdisk). I've run sync and 
unmounted/remounted /boot but that doesn't help.

grub-fstest seems to have no problem with reading from the filesystem:
# grub-fstest /dev/sda1 ls /grub/core.img
core.img
# grub-fstest /dev/sda1 blocklist /grub/core.img
655432+55,655487[0-414]
# grub-fstest /dev/sda1 cmp /grub/core.img /boot/grub/core.img; echo $?
0

/dev/sda is partitioned using GPT. /boot is a normal ext3 filesystem on 
/dev/sda1.

I've made the MBR [2] and sda1 (about 38MB) [3] available.

Final note: this exact setup worked just fine when I installed this 
system in mid-June. I can probably figure out the version of grub2 on 
the install CD if that would help.
