How to save OpenWrt settings

i use imagebuilder with files and package option, with a script on my linux desktop i rsync all my configuration, including ssh keys, passwords, all package settings and so to my files/ folder.. the result is a fully working image with my known good configuration 100% good to go, including all packages and settings, ready to be flashed at any time or after some testing gone bad a factory reset will reset to my 100% working factory settings.. this is also a very fast way to upgrade to minor release es. 19.07.7 to 19.07.8 i don't even bother to keep settings since all is already in my image.. just my 2 cents here :wink:
