Was looking into installing an updated version of ubuntu on an unmatched rev b device using nvme ssd as storage. Went to the distribution site here: Download Ubuntu for RISC-V Platforms | Ubuntu
and saw this quote next to the “Ubuntu Server preinstalled image” for unmatched rev b boards :
“If you have an NVMe drive, we advise you to use the Ubuntu Server live installer.”
Is there a specific technical reason why ubuntu suggests using the Ubuntu Server live installer versus the preinstalled image on an nvme ssd drive?
I think the reason is that the preinstalled image is made so that you copy it directly on the SD card, and then boot the system from the SD card, which can be significantly slower than from an NVME. With the installer image, you can flash that to the SD card, install on the NVME drive, and then change boot settings to boot from NVME, which will give you a significant speed up.
On the other hand, flashing the preinstalled image to the NVME drive can be more difficult and is not standard (but could work to achieve the same thing).
