Package: grub-common Version: 1.98+20100602-2 Severity: important grub-mkdevicemap produce device names such as /dev/hda or /dev/sda. However, these names can change over reboots. These device names are used (at least) in the /boot/grub/device.map and in the debconf prompt of grub-pc to choose disk to install grub into it.
Using these non persistant names leads to grave problems such as, during a upgrade of grub-pc, installing (due to grub-pc postint) grub on an external hard disk (/dev/sda this time) instead of the 'normal' hard disk. If /dev/sda is a usb key without partitions, this can even lead to data loss. I recently experiment this problem twice: one time with an external disk on /dev/sda when upgrading grub-pc, the second time when upgrading grub-pc after a reboot to a 'libata' kernel (/dev/hda -> /dev/sdX) Using /dev/disk/by-id/* when possible would be far better in my opinion.
