Failing at the first hurdle - Pi 02W, "can't read /etc/rc.local no such file or directory"

[heyho74]

Trying a fresh install on a brand new 02W.

Fresh install of RaspiOS-ARM64-Lite, updated, with the commands pasted in to expand the swap and switch off power saving, and I'm receiving "can't read /etc/rc.local no such file or directory"

sudo sed -i 's/CONF_SWAPSIZE=100/CONF_SWAPSIZE=2048/g' /etc/dphys-swapfile && sudo sed -i 's/#CONF_MAXSWAP=2048/CONF_MAXSWAP=4096/g' /etc/dphys-swapfile && sudo sed -i '/^exit 0/i sudo iw wlan0 set power_save off' /etc/rc.local && sudo reboot sed: can't read /etc/rc.local: No such file or directory

Hoping there is an easy fix so that I can move on to the actual install.
