Packaging talk:Alternatives

Is there a particular reason to require %{_sbindir}/update-alternatives instead if chkconfig? I thought generally we preferred the latter? Petersen 10:18, 14 November 2011 (UTC)

What is the purpose of %postun in the sendmail example? I mean this:

%postun
if [ "$1" -ge "1" ]; then
	if [ "`readlink %{_sysconfdir}/alternatives/mta`" == "%{_sbindir}/sendmail.sendmail" ]; then
		%{_sbindir}/alternatives --set mta %{_sbindir}/sendmail.sendmail
	fi
fi
