@Sebastian: You can check grub.cfg by running grub2-script-check.

i havn't got a clue what `grub2-script-check` does or how to invoke it, but running it as supersuser.... well.... it doesn't finish with the shiny new grub.cfg created by grub2-mkconfig. i left it running for about 10 minutes and all i can say is, that it's CPU efficient as it doesn't raise my load, but it never finishes. and as it's compiled i'm unable to "easily" debug it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
