Building Custom OpenWrt Images

I've been using OpenWrt on my routers for several years at this point but one of the things that has always bothered me is sysupgrades. A typical sysupgrade will always be a fresh installation and although you can restore your packages and configuration, this isn't an automatic process.

I started creating a script to make sysupgrades less painful but then I discovered OpenWrt image builder. There's also OpenWrt buildroot, which is basically compiling the entire project from scratch and the SDK which can be used to compile OpenWrt for a specific target.

The image builder should hopefully make OpenWrt sysupgrades pretty smooth. In my opinion, if you install a few packages or make significant configuration changes on your OpenWrt installation, you should probably create custom images using the image builder.
