Bug#542425: error: cannot find a device for /.

[Albin Stjerna]

Package: grub-pc
Version: 1.96+20090826-3
Severity: normal

I'm having roughly the same problem as the earlier submitter. I'm using the standard "Encrypted LVM" setup, and I have upgraded both LVM and GRUB as adviced earlier, with no success. Though, I haven't rebooted yet, fearing the system would be unbootable.


Output:

Setting up grub-pc (1.96+20090826-3) ...
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
