Thanks for this work!

In case you've not seen it before, shellcheck is a great linter for shell, and integrates with a bunch of editors (I use the this extension with vscode, fwiw).

It didn't find anything horrible here--just a few nits:

 shellcheck syno_create_m2_volume.sh 

In syno_create_m2_volume.sh line 79:

Feel free to close this issue--I just wanted to stop by and thank you for your work.

That's a well written guide. I might put a link to it on my readme page.

I do use shellcheck.

• The args="$@" is just so I can echo the arguments used. But I could change it args=("$@")
• The unused variables are for future use.
• Line 79 is something that does work when the script is in a different shell 9to check it's running in bash) even though shellcheck warns that it's not an "if, then, else".

ICYMI, you can prepend the line # shellcheck disable=SC2015 (or whatever the warning is) right above the offending line of code if you've checked out the linting error and have determined it's a false positive or otherwise ignorable. Docs are here.

Thanks again.
