management of mysql-keyring file

[Krzysztof Wróblewski]

Hi,
I'm trying to implement my own keyring file management mechanism on Linux OS.
I searched documentation and I didn't find any information when exactly MySQL accesses mysql-keyring file.

Would you like to confirm if it's safe to move keyring file (to other safe place) after MySQL starts?
When exactly I need provide mysql-keyring file to proper component directory pointed in configuration?

I found only that for migration purpose it should be on place before key rotation and during startup of mysqld. Anything else?

If it's somewhere described, I would be happy to read more about access file mechanism.
