+## SD card notes
+Many SD cards I attempted would boot fine but then fail to reset on reboot.
+Some preliminary research suggests that this may be a kernel issue, but I'm not
+entirely sure at this point. For now, I took the easy way out: Just keep trying
+SD cards until one works! Thankfully, it seems to be reliable that an SD card
+works either 100% or 0% of the time. Currently using a 32GB Microcenter cheapo,
+in place of the nicer 128GB ones I was planning on instead.
