| - | If you add packages to your installed version of OpenWrt (via opkg or LuCI), be careful to use the packages that are compiled specifically for the version of sysupgrade .bin you have running on your RouterBoard. | ||
| - | For example, if you decide to run nightly snapshots, be aware you'll want to also install and run the packages from that specific snapshot - each time you update the snapshot, you'll want to update both the sysupgrade .bin AND the packages you are using. | ||
