Hi folks, a couple days ago our power went out and our main mail
machine got caught by a grub bug that has caught a fair chunk of
machines since an update back in March. Anyway it took a lot of head
scratching to figure out what the problem was once I had someone with
eyes come bye to look at the screen I keep around for iritating
situations like this.
Chris Brannon came up with a really cool way of making the system more
accessible by hand writing a grub.cfg file. His suggestion was to use
a fairly new grub feature which provides a morse code output at the
initial boot grub prompt. You have to have a pc speaker or buzzer in
your machine but I'm sure it'd be useful even to folks that don't know
code because it outputs after different events.
I include my file below so you can modify it for your own hardware. I
also thank Chris for a wonderful suggestion.
