I figured this is more a noob Q
But I have a small army of Pis, and once I get a Pi the way I like it, I typically just dd it back to an image file on my Mac.
Problem is they are *huge* Full 16/32GB of the SD card.
So my overall Q is:
Can I just copy/rsync the rootfs partition? ie:
dd the original (small) raspbian image to a new SD, then mount and copy over from a folder on my Mac that has all the files from my set up? (My Mac can read/write extfs partitions just fine.)
I guess more to the point, is the rootfs delicate? Like it needs certain files in a specific location? Or is all that (un)happiness in the boot partition?
(A real longshot, we can't PXE boot these, can we?)
