Taking effect immediately of course does not mean that if I booted
using systemd and switched to openrc that systemd will be killed.
That idea makes absolutely no sense, it simply can not work. In
theory systemd could support execl() sysvinit and vice versa, but
I find that unlikely. The "take effect immediately" I believe that
you understood me to mean is simply impossible.

By take effect I mean that the filesystem should be modified in such
a way that the next boot will use what I selected. No further action
which could fail should be required beyond the eselect command.

Unless the eselect command has successfully modified the filesystem I
can't really know that my system will boot with what I have selected,
ie. eselect does not provide any useful feedback, because it can not.
