Hi,
Sorry for another Novice Question. I wanted to install a couple of packages - rsync (so I can backup the overlayfs) and nano (because I suck at vi 
). AFAICT they are both available per the package index (https://openwrt.org/packages/index/network---file-transfer and https://openwrt.org/packages/index/utilities---editors), and I've done opkg update which seems to work, and there are some packages available, just not either of these...

I've had a look round https://openwrt.org/packages/start and the packages FAQ, but I'm afraid I'm obviously still missing something obvious...
