@JeGoi is this currently done? Otherwise we should build this image like we do with FreeRADIUS.

I think we are already doing it https://www.packetfence.org/downloads/PacketFence/debian-lastrelease/14.1/pool/bookworm/p/proxysql/
BUT there is no automation for deb construction around that for now.
It like done by hand...
