sdm

I recently needed to create some heavily customized pi images for a fleet of Iot devices. I came across this tool that did the job nicely. Only downside is that it only works on Linux. https://github.com/gitbls/sdm

> You see, unlike Debian or other standard OS, Raspberry Pi OS (which I still call Raspbian in my head and likely use in this article multiple times) is designed to be flashed to the SD card directly and doesn’t actually have an installer that can be booted from USB https://github.com/gitbls/sdm can help with this issue.

Author here, thanks for pointing out the mistake! The USB controller speed is indeed 4 Gbps and not 4 GB/s, I have updated the post accordingly. > I believe the USB controller still shares a bus with the NIC, which means maxing out the network connection will affect disk rw performance. You could confirm this by observing a concurrent iperf affecting fio results. Thanks for the pointers, I didn't know about iperf! That's something I'll likely try at some point for the sake of completeness, although I have other projects competing for my attention. > Well, that's specifically AES precompiles. Just like for kopia, you can benchmark and change LUKS algo for something more suitable for the platform like xchacha20: https://rr-developer.github.io/LUKS-on-Raspberry-Pi/ Absolutely, that disk was encrypted using xchacha20. I used the excellent sdm
