You don't need prayers to ensure you can continue to run your software. It's unrealistic Linux can ever change to a different license than GPL2. Note, however, that this hasn't stopped Linux from being used as giant spyware (Android) and being overtaken by a single entity (RedHat) slowly eroding it (Systemd, Docker).

If you're concerned, I'd recommend basing your software on POSIX and make it also run on the BSDs, rather than just Linux, and in particular avoiding Linuxisms such as Docker and Systemd which you'll find are poorly designed anyway.
