Arch Linux Install Speedrun Any% Scriptless

So I got a 0:55.06. Timed without the boot of the iso. Timed from the first character typed (f) to the moment the tty shows up on the install.
Anyone who wants to host/make a website to host speedrun times or do something more formal I would be glad to collaborate just comment your discord username here ig and I'll talk with you.
Commands:
fdisk /dev/sda
n
[a ton of enters]
w
mkfs.ext4 /dev/sda1
mount /dev/sda1 /mnt
cd /etc/pac-cache
pacstrap -U /mnt *
arch-chroot /mnt bash -c 'grub-install /dev/sda; grub-mkconfig -o /boot/grub/grub.cfg;'; reboot
For some reason the fstab isn't needed so that provides less stress (I started typing it but ran ctrl+U). I created a custom arch iso with the 113 packages installed on a minimal arch install (pacstrap /mnt base linux grub) cached in /etc/pac-cache. One time save is to have a better dir for pac-cache and/or finding packages that aren't needed for an install and removing them.
Making the iso is pretty easy.
1. Do a minimal arch install and send the list of all installed packages to a file
2. Mount the virtual disk and run pacman -S --cachedir /path/to/archiso/airootfs/etc/pac-cache - [less than sign but youtube won't let me put it] packagelist.txt
3. ctrl c before it installs but after every package is downloaded
4. build the arch iso. should be about 1gb.
5. Enjoy your arch iso that increases the speed of the install
