-## Using a Raspberry Pi Zero
-
-Linux devices can emulate USB mass storage devices (and other kinds of USB devices).
-
-However, powering a Linux device using a USB port might draw more current than it is safe, damaging the device powering the Linux device (e.g. a laptop you want to boot from USB).
-
-A simple option is getting a Raspberry Pi Zero (I used the 2 W model) with the [EP-0097](https://wiki.52pi.com/index.php/EP-0097) USB adapter.
-This should be safe.
-However, without any additional setup, the procedures I describe only work when using an always-on USB port.
-
-(Assembling the Raspberry Pi Zero into the USB adapter is straightforward.
-However, I was confused: you must mount the thin acrylic shield below the USB dongle extension board, then the thick shield over the board, then the Raspberry Pi.)
-
-1. Use the Raspberry Pi Imager to create a MicroSD card for your Raspberry Pi Zero, configuring remote access via SSH and your wireless network.
-1. Add `dtoverlay=dwc2` to `/boot/firmware/config.txt` to enable USB trickery, as per [the adapter instructions](https://wiki.52pi.com/index.php/EP-0097#For_the_latest_Raspberry_Pi_OS).
-1. Connect the Raspberry Pi with the adapter into an always-on USB port of the device you want to use.
-1. Stall the device boot process until you set everything up on the Raspberry.
-1. Connect via ssh over wireless to the Raspberry Pi.
-1. Download the image you want to use.
-1. Use the `rmmod` command to remove any modules starting with `g_`.
-1. Run `modprobe g_mass_storage file=/path/to/image`
-1. After running this command, the device should be able to boot the image.
-
-### Notes
-
-* You can run a command such as `while date ; do sleep 1 ; done` to monitor that the Raspberry Pi does not reboot or poweroff.
-
-### Ideas
-
-Create an automated process that:
-
-* Installs Raspbian lite to an SD card
-* Alters the SD partitions to create a large UDF partition
-* Enables a systemd service on boot that exposes `/udf/image` as USB mass storage
-* Then users can either manipulate the SD card through SSH, or by mounting the UDF partition
-* `/udf/image` can be a symbolic link
