my 1st time trying to set up a pi4 1gb as a openwrt router and its driving me round the twist. mainly around the expanding of the FS. I only use linux versions on my other Pi's and don't have another system with card reader that has Linux installed on it. so I'm totally stuck as I believe the only way to resize the fs is via another linux machine?
I have found a few images with expanded fs online, but they all have other customisations that im not interested in. Basically im after a vanilla snapshot for a Pi4 that has an expanded fs and nothing else in ext4
does anyone know either a way to expand the FS live on the unit or where i can DL an img file with an expansion already done.
cheers
