One way to learn grub is to debug problems. Grub2 is pretty clean, particularly the version with the new Fedora 18
sudo grub2-mkconfig >/tmp/grub.cfg is what I run I then study /tmp/grub.cfg and while the rule is to not make changes, (since a kernel upgrade will cause a new version to be written), I do remove groups of menu items and I change default from '0' to the linux of choice (my system has 4 different distributions) When I am happy with my tinkering of my /tmp/grub.cfg, I do a sudo su I cp /boot/grub2/grub.cfg /boot/grub2/grub.bak # always have a backup I then cp /tmp/grub.cfg /boot/grub2/ Regards Leslie Mr. Leslie Satenstein 50 years in Information Technology and going strong.

If you want security you might add a grub password, http://www.gnu.org/software/grub/manual/grub.html#Security but also keep in mind the comment made in that documentation: By default, the boot loader interface is accessible to anyone with physical access to the console: anyone can select and edit any menu entry, and anyone can get direct access to a GRUB shell prompt. For most systems, this is reasonable since anyone with direct physical access has a variety of other ways to gain full access, and requiring authentication at the boot loader level would only serve to make it difficult to recover broken systems. If this isn't a physically locked down kiosk then adding any type of obstacle to the bootloader won't prevent an intruder from booting from other media, replacing the hard drive, adding a hardware keylogger, or any multitude of other options available to someone with physical access to the machine. -- Jordan Uggla (Jordan_U on irc.freenode.net) _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
