I have patches here in the queue to skip the SD card, FWIW, but... Knowing you and knowing the RPi5, I strongly suggest you have a look at alternate platforms; my personal favourites are rk3588 based; YMMV. The Pi5 NVME IF has only a single lane, which only works reliable at Gen2 speed. To compare, the Rock5B I'm currently typing to has a quad-lane Gen3. The Rock 5B+ splits that into 2x2 Gen3 if you prefer. There are some boards with 2.5Gb Ether, if you want to extend into NFS. The quad-core CPU is not bad, but the current state seems to be to add at least 4 more "little" cores, if not another 4 medium-sized ones. So long story short: the Pi5 might not be the best choice starting already with the hardware, let alone the documentation. HTH, Torsten
