configure GRUB

[boredsquirrel]

This is critical. On OSTree you need to be able to switch back, but by default grub is set to skip the menu. This also breaks dual booting with another OS.

Also styling it nicer with this tool should be an option for a general modern experience

Disable autohide:

This is an intentional feature but may be unwanted. An option to run

sudo grub2-editenv - unset menu_auto_hide

will be useful

[boredsquirrel]

The grub styles run without errors if you replace the THEME_DIR="/usr/share/grub/themes" with something else.

git clone https://github.com/vinceliuice/grub2-themes.git
cd ~/grub2-themes

sed -i 's/THEME_DIR="/usr/share/grub/themes"/THEME_DIR="/var/usrlocal/grub/themes/d install.sh"

xdg-open README.md

You have to follow the README

[boredsquirrel]

sudo grub2-switch-to-blscfg

is supposed to remove double entries. In Fedora 38 there will be a fix too, so may not be needed

[boredsquirrel]

Someone on Fedora Discussion had this in their post install to fix grub on EFI:

if [ -d /sys/firmware/efi ]; then
  grub2-switch-to-blscfg
  grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
else
  block_device=$(lsblk -spnlo name $(grub2-probe --target=device /boot/grub2) | tail -n1)
  grub2-install $block_device
  touch /boot/grub2/.grub2-blscfg-supported
  grub2-mkconfig -o /boot/grub2/grub.cfg
fi

if you want a nice grub style, this has to be ran afterwards. For some reason it also fixes the grub style.
