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?

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
    -> make our own or extract kb selection, mirror selection, and time zone selection (if feasible) to hijack them for our purposes
  - warn user about formatting and making the USB stick unusable with Windows
  - select kb layout
  - set up disks
    -> select disk from a list
    -> wipe disk (new gpt)
    -> partition disk
      -> 270M ESP (if needed) or 2M BIOS GRUB
      -> partition that holds home and the squashfs image
    -> format partitions (use force option)
      -> ESP FAT32
      -> rest F2FS
  - mount them things, set up tmpfs as / for now
  - install base system
    -> select mirror
    -> select installation type (x86_32/x86_64/aarch64, glibc/musl)
    -> 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
    -> configure XBPS (set mirror, anything else?)
    -> configure sudo
      -> drop a file with "%wheel ALL=(ALL:ALL) ALL" in /etc/sudoers.d/sudo_group
    -> configure overlayfs setup
    -> configure tmpfses
    -> configure /home (bind mount or symlink?)
    -> configure keymap (etc/rc.conf)
    -> configure shutdown squashfs updater
      -> rc.shutdown?
    -> configure and install bootloader
      -> determine BIOS or UEFI
      -> if UEFI, install as removable device
    -> 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
    -> set up timezone
      -> ask user which zone
      -> ask user whether to use UTC or local time
      -> configure (rc.conf and /etc/localtime)
    -> set hostname
      -> ask user
      -> configure
    -> 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
      -> ?? xorg-fonts pulsemixer PrismLauncher
      -> 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
