Changing boot and tmpfs partition mount options to noatime to preserve USB boot life

I’ve been running Scale quite happily booting off a large high-quality USB stick as my NAS case doesn’t have room for any other boot device and I back up my config file religiously externally. This is only a home server.

I noticed that both the boot partition and the tmpfs partition are mounted with relatime option. Could I modify that to the noatime option to cut down on the usb drive wear? Any downsides? Would such a modification survive truenas version upgrades?

It’s suggested to use a SSD or NVMe in a USB adapter for the boot-pool, if you have to use USB.

Others will comment on your wanted modifications.
