Possible to get Plymouth to work on Dietpi?

Hi,

I’ve been playing with the concept to cover up the boot messages on startup and shutdown for the DietPi, thought it could be handy for some people who want to provide DietPi’s to non-technical users. Tried following RPi guides but most are out of date and don’t work for me. If it could be included in the package that would be cool. If not, I wouldn’t mind a nudge in the right direction.

Thanks!
