ThinkPad X270 RAM upgrade

Since 32 GiB SO-DIMMs are cheap at the moment, I decided to try an upgrade my ThinkPad X270 from it’s current 16 GiB RAM to 32.

Ansible and Sailfish OS

Since I seem to set up new Sailfish OS devices at least once a year (because I got myself a new toy) and I am lazy, I set up my current Sailfish OS device, a Gemini PDA, up to work with Ansible.

These are my notes on using Ansible with my Gemini PDA running Sailfish OS 3.0.1.14

Some of the following steps are specific to my HP ProLiant MicroServer, but most will apply to any modern linux and HW (one would prefer the TPM to be an integral part of the motherboard as opposed to a module).
