Bug#465033: grub-pc: grub-setup fails to open the root-device if it is on a LVM

[Michael Guntsche]

Package: grub-pc
Version: 1.96+20080209-1
Severity: important

With  build 20080209 grub-setup is no longer able to install on a
lvm root-device.

With the previous version (20080203) it worked.

grub-setup -vvvv -r '(fatoftheland-main)' '(hd0)'grub-setup: info:
prefix = /boot/grub
grub-setup: info: getting the size of /boot/grub/boot.img

With the current version I get:

The core.img file is the same.
