This is mostly based on [kowalski7.cc.xyz instructions](https://kowalski7cc.xyz/blog/systemd-boot-fedora-32/) which also tells
more clearly what to do. These are my notes on what I have done on top of it
and probably not very much comprehensible by others than me.

## Installing Fedora?
Boot Anaconda with the flag `inst.sdboot` to not have to install systemd-boot
later.
## Converting to systemd-bootd later
1. `sudo mkdir /efi`
1. Edit `/etc/fstab` mmounting the EFI partition to `/efi`
1. `sudo mkdir $(cat /etc/machine-id)` also note the machine-id, it's used a
lot.
1. `sudo dnf install systemd-boot-unsigned sdubby -y`
1. `cat /proc/cmdline` noting it, it will become included in
`kernel_cmdline=""` in `/etc/dracut.conf.d/99-cmdline.conf` (or other
freeform name as long as it ends to .conf?) Might also be worth it to note
other dracut configuration files including defaults
`/usr/lib/dracut/dracut.conf.d`
1. TODO BOOTCTL INSTALL FROM ARCH WIKI?
1. TODO `printf "\tsudo mkdir /boot/%b/%b\n" "$MACHINEID" "$EXPECTEDKERNEL"`
1. TODO `printf "\tsudo kernel-install add %b /lib/modules/%b/vmlinuz\n" "$EXPECTEDKERNEL" "$EXPECTEDKERNEL"`
1. The original instructions said to `sudo dnf reinstall kernel-core`, but
this has deviated with systemd-uki. They also said to `sudo bootctl` to
see if it got installed properly before...
1. `sudo reboot`
1. TODO: PROTECTED PACKAGES SHELL-THINGS!
I saw an instruction somewhere about `sudo lsinitrd` displaying what is within
the image, but that doesn't seem to be the case for UKI. TODO!

# REMOVE ME UPON CONFIRMING THE ABOVE IS CORRECT
1. Read https://kowalski7cc.xyz/blog/systemd-boot-fedora-32/ very helpful and base of this
2. Anaconda inst.sdboot
3.efi mounttaus /efi, fstab
3. Mkdir /efi/machine-id
4. systemd-boot-unsigned sdubby
5. cat /proc/cmdline
6. dracut asetukset
7. bootctl install
8. kernel-install add
9. dnf reinstall kernel-core? Ei liene tarpeen, koska uki?
10. Sudo bootctl
11. Reboot
Note protected packages. Shell-things, grub?
