	# Append mounted config to final config
	grep -v -E "$reArgSkip" < "$userConfPath" > "$userConfFinalPath"

According to the comment (# Append mounted config to final config), the intention of this code is to append, not overwrite.
Shouldn't it be >> "$userConfFinalPath", not > "$userConfFinalPath"?

EDIT:
I just realized that it is the first code that may create the $userConfFinalPath file, and that it does not overwrite any existing configuration.

Nevertheless, we should use >> rather than > as a convention when we intend to append rather than overwrite.

This is because the code > "$userConfFinalPath" can cause confusing bugs when the code is changed in the future or when a third party clones this repository and changes the code.
