Description
litd stops with a "successful" exit code 0 when it stops upon lnd exiting due to a failure and a non-0 exit status code.
Expected behavior
litd to exit with a non-0 exit code since it's stopping unexpectedly (and lnd presumably stopped unexpectedly as well).
Actual behavior
litd exits with a 0 exit code.
To reproduce
Have litd and lnd running - I have them running in systemd. Shutting down bitcoind causes lnd to exit with a failure status code while litd exits with a 0 code.
System information
I'm using litd binaries downloaded from github with a separate standalone lnd instance. This is on a rpi4 arm64.
Below are systemd status logs from lnd and litd (with some extra log output for litd) that shows lnd having exited with 1/FAILURE while litd exits with 0/SUCCESS.
