I changed my System shortly from XFS to ReiserFS. The current Grub-Version used in Gentoo (Grub 0.90) had some Problems with not recognizing ReiserFS. So I unmasked Grub 0.92 and installed it. It recognized ReiserFS and was installabled from the grub-shell without problems. But at the first reboot, it didnt display the menu. I double and tripple checked my menu.lst for typos but it was 110% correct. Plus I could boot the system from the shell. After some trying and guessing, I renamed the menu.lst to "grub.conf" and ...BANG... it works! I couldnt find anything about a naming change in the Grub Changelog, but this should be tested by others, too.
The last line of the ebuild states that menu.lst has been renamed to grub.conf in this release. Perhaps either red texting that message, or doing a dosym from menu.lst to grub.conf might make it easier/break less?
i think the dosym idea would be good ... just checking to see if grub.conf exists and if not, sym-linking it to menu.lst and informing the user would generate a lot less headaches :)
submitted grub-0.92-r1 which fixes this bug. (see bug #6820) Markus
