I just enabled mysql support in postfix rpm. When I upgraded postfix package on my test machines, I got errors because yum installed postfix first and after postfix it installed mysql. When postfix: Requires: mysql shouldn't yum install those req's first? Now package upgrade won't work correctly because mysql libs are missing when postfix commands are run on %pre scriptlet to update old config to new format. -- Tuomo Soini <tis@xxxxxxxxx> Linux and network services +358 40 5240030 Foobar Oy <http://foobar.fi/>
