I’m running CE 19.1 on a 32Gb SD… all media storage is out in my network so 32Gb is overkill. I’d like to have an image backup that is NOT 32Gb in size, allowing me to restore to alternative SDs that could be smaller and/or faster and/or more reliable.
In Raspberry PI land, this is a “shrunk image” that expands to fill the filesystem on first boot. CE does this too using the downloadable production images.
How do I do this? All the R-PI guides use tools that are not available in the stripped down CE environment. Any help would be appreciated.
