[Openswan dev] Why does pluto need ipsec and whack?

[Daniel Djamaludin]

Hello,

Does anyone know the background as to why pluto needs to have the configuation read by the ipsec configurator and then passed onto whack which then prods pluto? I'm curious as to why pluto wasn't designed to just read the configuration files for itself and any changes to the files to be updated with a SIGHUP signal. Is there something fundamental to the behaviour of pluto that I'm missing here?

Thanks for your time.
