Should now work with the guide out of the box again with this PR:
https://github.com/pimatic/pimatic/pull/1040

Maybe we could add the commands helping with debugging this in the init script?
Something like this before the pimatic service is started:

which node > /tmp/pimatic_daemon_node.path
node --version > /tmp/pimatic_daemon_node.version

I’m suere someone could also append these to the pimatic-daemon.log with some commandline FU for figuring out the current install location of pimatic.
