„uci set“ will only make temporary changes which can be found in
/tmp/.uci. That dir acts as some kind of overlay...
"uci commit" will write those changes to the filesystem/flash.
It doesn't matter whether you use the command line tool or lua
bindings... „Commit“ will kill your flashchip in the long run :D.
Ordinarily OpenWrt doesn't do any write to flash without user interaction.
