(not sure to have used the right words in the title)
After installing Openwrt on my routers, I install several other additional packages.
Sometime it has happen that tinkering too much forces me to reinstall OpenWrt from the beginning, and so I have to reinstall all the previous additional packages.
Is it possible to create an install image so that in case I can reinstall Openwrt from it and have, apart the configuration settings, all the other packages I previously installed ready to use?
Thank you.
