There is no real benefit from that - sorry
The about only thing that comes to mind is to Get latest openHABian and enable the new zram feature, it “moves” directories into RAM, avoiding writes to SD card. This isn’t done for all but the most write-intensive dirs, but you can enable it for more directories (edit
/etc/ztab) to make use your memory.
openHABian default is 350m which is enough for about any install I’ve seen to date.
