I was thinking it would be nice to have for backups, but maybe even going as far as mounting ~/home to be able to run from multiple machines. I’m really asking where to get started looking without crashing into marketing department nonsense and search engine steering bias.
Yes. My experience with the gl-inet device I have was that initially the fork was good enough and when the company didn’t update it much anymore, it was very easy to reflash the device to a main-line OpenWRT version. It’s now working great with the latest mainline version despite being quite old already.
