[gentoo-dev] How should I kill a daemon from an ebuild file?

[Jules Colding]

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()?

Or is this ultimately a big no-no??

Thanks,
  jules
