==Updating grub== | |||
Sometimes there is also an update for the GRUB package itself. So far, the grub package is updated, but this new GRUB is not automatically installed in the boot area. | |||
You can do this manually following the instructions above. Or you can install the Grub Maintainer Script ''install-grub''. It should work flawless for the majority of people, but SecureBoot, ZFS and fancy encryptions are not supported yet. | |||

===install-grub=== | |||
is another script that does update the installed bootloader that runs when you turn your computer on.
