If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Full Source Code: https://github.com/varunon9/DynamicWallpaper/tree/always_running_service

Steps-

Create a Foreground Service (MyService.java)
Create a Manifest registered Broadcast Receiver (MyReceiver.java) which will start your Foreground Service
In onDestroy lifecycle of MyService, send a broadcast intent to MyReceiver
Launch the MyService on app start from MainActivity (see step 8)
With above 4 steps, MyService will always get re-started when killed as long as onDestroy of Service gets called
onDestroy method of Service is not always guaranteed to be called and hence it might not get started again

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.
