How should I kill a daemon from an ebuild file?

Hi,

I have an ebuild (see below) for a small keyring daemon. I
would like to
kill the daemon process, if it is running, whenever it is
emerged again
to ensure that no running daemon process refers to an old
install.

Is there a clean and recommended way of doing this in an
ebuild or
should I just use killall in pkg_postinst()?

Thanks,
  jules

You might wanna check the -dev mailing list to be sure, but
I'm almost
certain that they'll tell you this is a no-no.  Generally
speaking
ebuilds should build/install packages and not affect the
system in ways
like starting/killing processes. A simple ELOG message is
the preferred
method.

Nevertheless, the -dev list is probably the better forum to
answer your
question.
