I think this e-mail did not go through.
Package: grub-pc
Version: 1.98+20100804-14
Severity: normal
Tags: patch
Does not work with root over nfs as well. Was upgrading from lenny to
squeeze and update-grub failed:
aviastopas:/usr/sbin# update-grub2
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev
mounted?).
digging with bash -x...:
aviastopas:/usr/sbin# grub-probe --target=device /
grub-probe: error: cannot find a device for / (is /dev mounted?).
Quick hack working for me is here. Of course, it will break "normal"
systems:
aviastopas:/usr/sbin# diff grub-mkconfig.*
152c152
< GRUB_DEVICE="`${grub_probe} --target=device /`"
---
> GRUB_DEVICE="`${grub_probe} --target=device /boot`"
When I changed it, update-grub fully worked and this was the only issue
while upgrading to squeeze. Wheee :)
