Simple guide for fulldisk encryption with Proxmox and ZFS native encryption

Install normally using the installer, after the setup reboot into recovery mode (from the USB stick). Make sure to install in UEFI mode (you need systemd-boot).

If the USB stick is not working for you, because of the old Kernel version (2.6.x), you can also use an Ubuntu 19.10 / 20.04 boot stick. ZFS suport is enabled there out of the box.

Steps:

I needed to quickly encode a protobuf from the command-line, and while I pretty much immediately came across protoc --encode as the obvious solution, I did not find much documentation on the input textual syntax.

Here is the relevant snippet from protoc --help:

--encode=MESSAGE_TYPE       Read a text-format message of the given type
                              from standard input and write it in binary
                              to standard output.  The message type must
                              be defined in PROTO_FILES or their imports.
