Alright, so this started happening again. I'm using the latest version from unstable, 1.97-1. Did and apt-get remove --purge grub-common grub-pc, then removed everything in /boot/grub, and reinstalled. [20:15 @laptop ~]% cat /boot/grub/device.map (hd0) /dev/sda [20:15 @laptop ~]% sudo grub-probe -t device / /dev/mapper/lvm-system [20:16 @laptop ~]% sudo grub-probe -t abstraction -d /dev/mapper/lvm-system grub-probe: error: no mapping exists for `lvm-system' After adding '(lvm-system) /dev/mapper/lvm-system' to /boot/grub/devices.map: [20:17 @laptop ~]% sudo grub-probe -t abstraction -d /dev/mapper/lvm-system <nothing> Of course, the generated grub.cfg file doesn't contain any 'insmod lvm' directive. As previously, the files in /dev/mapper/ are real block devices and not symlinks. If there's anything I can do to help debug this issue, please let me know. Regards, -- Albin Tonnerre
