Entrypoint script wipes data dir
I've been hit with this multiple times today, and it was really confusing until I figured out the reason. So I would make a new blank node dir with a data dir for a fresh snapshot import;
mkdir -p node/data. Then import the snapshot, all good. But as soon as I start the node after, my freshly imported data is wiped from disk
Turns out line 60 in entrypoint.inc.sh thinks it's OK to just wipe the entire data dir if the
alphanet_version file does not exist. A snapshot import does not create this file, so yeah - data gone
It would be great if the script could be a bit less intrucive and instead perhaps show a suitable error message and exit or something.
