GRUB

The bootloader is what the machine’s firmware (BIOS, UEFI) hands off control to once it is done thinking.

Alpine will use GRUB as the bootloader if it detects that is being installed on a machine that uses UEFI firmware.

This is done by /usr/bin/setup-disk, which runs as part of setup-alpine.

setup-disk -h | head

usage: setup-disk [-hLqrve] [-k kernelflavor] [-m MODE] [-o apkovl] [-s SWAPSIZE]
                  [-w FILE] [MOUNTPOINT | DISKDEV...]

Install alpine on harddisk.

GRUB stands for Grand Unified Bootloader.

Updating GRUB settings

The (easily) tweakable parts of GRUB config are in /etc/defaults/grub. After making a modification, we need to update GRUB by doing, well, update-grub.

Here’s me removing the wait on the boot menu.

sed -i -E 's/GRUB_TIMEOUT=\d+/GRUB_TIMEOUT=0/' /etc/default/grub
update-grub
