sudo not actually needed for running rpiboot if debian package installed (which is how the instructions say to install)

	==== on Linux
	To set up software on a Linux host device:
	. Run the following command to install `rpiboot`:
	+
	[source,console]
	----
	$ sudo apt install rpiboot
	----
	. Connect the IO Board to power.
	. Then, run `rpiboot`:
	+
	[source,console]
	----
	$ sudo rpiboot
	----
	. After a few seconds, the Compute Module should appear as a mass storage device. Check the `/dev/` directory, likely `/dev/sda` or `/dev/sdb`, for the device. Alternatively, run `lsblk` and search for a device with a storage capacity that matches the capacity of your Compute Module.
	TIP: Alternatively, you can https://github.com/raspberrypi/usbboot[build `rpiboot` from source].

you suggest installing a debian package on linux and then later as part of that process suggest using sudo to run rpiboot

$ sudo rpiboot

However, sudo is not needed using these instructions. The debian package installs a UDEV rule in /lib/udev/rules.d/70-rpiboot.rules which avoids the need for sudo.

Strange. I've always had to use sudo to run rpiboot. I wonder if this has changed recently? Or have I simply always used it unnecessarily?

[AndySchroder]

If you compile from source, then sudo is needed. If you use the debian package, it seems you don't. Are you able to confirm?
