Re: pi vs swap on flash



I finally looked at piclone source, it uses parted to do the partition
stuff, cp to do the actual copying, the GUI is GTK.  And it's written
in C with popens.  https://github.com/raspberrypi-ui/piclone or more
directly https://github.com/raspberrypi-ui/piclone/blob/master/src/piclone.c
