Thank you for the information.
Is fork still to be an experimental parameter?

As it is commonly used, it is not mandatory as myself, so for the moment I think whether to deal with the parameter removed.

If you run kresd without (direct) systemd supervision, the -f parameter should work well, even though it's a setup that doesn't currently get as much testing as the single-process mode.  You can also simply run multiple kresd instances over the same cache - the only difference is missing a shared communication channel, in particular the `map` lua function that runs a lua command in all the connected instances.
