A concise comparison of operating systems. Some focus on root-on-ZFS, and on Plasma. Not intended to be comprehensive.

Describing availability is not necessarily a recommendation to install what's available.

The systems

Install Xcode from App Store or install Command Line Tools on your Mac running on Apple Silicon.

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

sudo apt-get install openvpn

sudo cp -r /usr/share/doc/openvpn/examples/easy-rsa/2.0 /etc/openvpn/easy-rsa2

cd /etc/openvpn/easy-rsa2

Connect the SD card to your computer and open the terminal.
