☝️ The project is now hosted at codeberg.

1. The user chooses storage profile and software selection.
2. Have a storage profile that support LUKS devices that are unlocked outside the installer
3. Have a storage profile that supports automatic disk unlocking via tpm.
4. systemd-boot by default
5. zswap by default, no systemd-oomd
6. Before making any changes on disk, the installer will pause and ask for confirmation.
7. Minimal installation should be possible with just 20GB of disk space.

• Based on the "Everything" fedora spin.
• Anaconda is only used as an entry point. In kickstart terms: the entire installation happens in "%pre".
• The installer is written in bash.

The "lvm_luks" storage profile creates these partitions:

[core@box ~]$ lsblk -i -o NAME,TYPE,FSTYPE,LABEL,SIZE,MOUNTPOINTS
NAME            TYPE  FSTYPE      LABEL      SIZE MOUNTPOINTS
sda             disk                        25.9G
|-sda1          part  vfat        EFISYS       2G /boot/efi
`-sda2          part  crypto_LUKS pvroot    23.9G
  `-luks        crypt LVM2_member           23.9G
    |-luks-root lvm   ext4        luks-root    8G /
    `-luks-home lvm   ext4        luks-home    2G /home
zram0           disk  swap        zram0        8G [SWAP]

• Before luks unlocking, there is only EFISYS and an encrypted partition "pvroot".
• After luks unlocking, "pvroot" contains an lvm volume group.
• It's lvm, so you can resize or add partitions later. For example, a second swap device.
• Reinstall-behaviour: If the installer sees a label "pvroot", it will ask for the LUKS key. If unlocking succeeds, any partition inside except "luks-root" will be preserved.

Run make. This should create early.tgz and late.tgz.

Now that you have these files, start a server. Here's an easy way to do both:

make && ./serve

Write down the http address that is printed, and append "manual.cfg". For example: http://192.168.178.22:3001/manual.cfg

Configure kernel and initrd (sample URLs, use a mirror close to you):

kernel https://ftp.halifax.rwth-aachen.de/fedora/linux/releases/43/Everything/x86_64/os/images/pxeboot/vmlinuz inst.ks=http://192.168.178.22:3001/manual.cfg
initrd https://ftp.halifax.rwth-aachen.de/fedora/linux/releases/43/Everything/x86_64/os/images/pxeboot/initrd.img

If you have secure boot enabled (n.b.: doesn't work), you also need to configure a shim:

shim https://ftp.halifax.rwth-aachen.de/fedora/linux/releases/43/Everything/x86_64/os/EFI/BOOT/BOOTX64.EFI

When everything is configured, start the installation:

boot

Read more about iPXE: iPXE commands, iPXE installation and EFI.

If you do not use iPXE, you will need to download an "iso file". Here's a sample download url: https://ftp.halifax.rwth-aachen.de/fedora/linux/releases/43/Everything/x86_64/iso/Fedora-Everything-netinst-x86_64-43-1.6.iso

If you use virtualbox or some other VM, you should be able to boot the iso file directly.

If you do not use iPXE or a VM, you may need to create an "installation medium" from the iso file. For example, a usb drive. There are plenty of tutorials for this on the internet.

When you boot the installation medium, you will see a black "grub menu". Press up or down arrow key to cancel the timeout. Then, navigate to the first option "Install Fedora". Press "e" to edit the installer's kernel command line options.

At the end of the line starting with "linux", add an option inst.ks=http://192.168.178.22:3001/manual.cfg, assuming your http server runs on 192.168.178.22.

• add "btrfs" storage module
• add "bcachefs" storage module
