make it bootable with UEFI and BIOS?
compare sizes of glibc and musl installations
try running multiple MC versions on musl
need xdg menu maker?

ideas:
use shell script for init, call real init via exec
system lives on squashfs
  -> overlayfs with tmpfs set up at boot
  -> new system image generated and written back on shutdown
    -> user-selectable ("Do you want to save changes to the system? This will take some time.")
    -> fstrim (if applicable)
swap on zram
f2fs for home
tmpfs for package cache, /tmp, logs?

when backing up
- do not cross file system boundaries
- exclude /tmp, package cache, logs

Steps to install:
  - (user does this:) boot Void installer
    -> log in as root
    -> connect to the internet
    -> download and run install script
  - preparations:
    -> update xbps
    -> install xmirror squashfs-tools
    -> make our own or extract (if feasible) kb selection and time zone selection to hijack them for our purposes
  - select kb layout
  - set up disk
    -> select disk from a list
    -> warn user about formatting and making the USB stick unusable with Windows
    -> allow user to double check that it’s the USB drive
    -> wipe and partition disk (new gpt)
      -> 2M BIOS GRUB
      -> 268M ESP
      -> 1G /boot
      -> rest /container
    -> format partitions
      -> ESP FAT32
      -> /boot and /container F2FS
  - mount them things
    -> set up plain tmpfs as / for now
  - install base system
    -> select mirror
      -> just use xmirror and get the result from the file
        -> if musl repo, remove that bit from repo url
    -> select installation type (x86_32/x86_64/aarch64, glibc/musl)
      -> if musl, add that bit to repo url
    -> install packages
      -> linux bash shadow f2fs-tools dosfstools dbus NetworkManager iana-etc iw wpa_supplicant util-linux which tar man-pages iproute2 iputils wifi-firmware traceroute grep gzip file sed gawk less coreutils findutils diffutils pciutils usbutils tzdata base-files ncurses mdocml procps-ng kbd xbps sudo ethtool kmod eudev runit-void removed-packages nano acpid squashfs-tools
    -> configure XBPS mirror
    -> configure sudo
      -> drop a file with "%wheel ALL=(ALL:ALL) ALL" in /etc/sudoers.d/sudo_group
    -> configure overlayfs setup
      -> startup script
      -> shutdown squashfs updater
        -> rc.shutdown?
    -> configure fstab
      -> /boot, /boot/efi
      -> /home (bind mount)
      -> NOT /, /container
    -> configure rc.conf
      -> keyboard layout
      -> hardware clock set to UTC?
    -> configure time zone while we’re at it
      -> selection dialog?
      -> symlink /etc/localtime
    -> configure host name
    -> configure and install bootloader
      -> if x86 install for both UEFI and BIOS
        -> Is there a way we can make this work with 32-bit AND 64-bit EFI at the same time?
      -> if ARM install only UEFI
    -> xbps-reconfigure -fa
    -> prepare 2nd stage installation
      -> auto login root
      -> put script in .bashrc
    -> build squashfs
    -> (if needed) set up an initramfs with busybox to mount the squashfs/overlayfs at boot time
  - prompt user to reboot to finish installation
  - second stage installation
    -> configure services
      -> dbus
      -> NetworkManager
      -> acpid
    -> ask user to connect to network using nmtui
    -> install packages
      -> setxkbmap xauth xorg-video-drivers mesa mesa-dri xorg-server elogind xorg-input-drivers xrandr acpilight xhost xinit xrdb xinput xgamma xset iceauth sessreg transset xcmsdb xkbutils xmodmap dejavu-fonts-ttf
      -> terminal?
      -> browser?
      -> prism launcher
      -> java (multiple versions?)
      -> pipewire (pulsemixer?)
      -> ask about nvidia driver
        -> install if needed
      -> ask whether to use CTWM or IceWM
        -> short description of up and downsides
        -> if CTWM, also install
          -> xclock
        -> if IceWM, also install
          -> network-manager-applet
          -> sound applet
        -> configure zram swap
    -> passwd -l root
    -> populate /etc/skel
      -> ultimate bashrc bc why not
      -> first run message in xinitrc
        -> auto-deletes itself
        -> displays README.txt on root dir of the F2FS partition
      -> if using CTWM
        -> put xclock in xinitrc
        -> configure more sane defaults
      -> prepend bashrc with a thing that checks of xorg is running
        -> if not, run startx and ask user whether to shut down, reboot, or do nothing afterwards
    -> set up user
      -> ask for username
      -> run useradd (non-interactively)
      -> run passwd (interactively)
      -> add to groups
        -> including sudo group
    -> build new squashfs image and reboot
