I noticed a problem installing thunderbird onto my system today using yum install. It wanted to install both the i386 and x86_64 packages instead of just the x86_64 package. That makes no sense whatsoever. I have exactarch=0 so I can install i386 packages if I wish but if I don't specific the arch it should install the x86_64 package because my system is x86_64. It definitely shouldn't be installing both. My recommendation is to deprecate exactarch and to have yum work the following way. 1) if you update packages that in installs the same arch(es) as is already installed. 2) If I install a package it should install just the basearch package unless told otherwise by the .arch extension. An additional extension (.all) can be used to may yum install all available arches. This should cover every situation that I can think of. -- Mark Lane, CET -- mailto:mark@xxxxxxxxxxxx Sales Manager -- Hard Data Ltd -- http://www.harddata.com T: 01-780-456-9771 -- F: 01-780-456-9772 11060 - 166 Avenue Edmonton, AB, Canada, T5X 1Y3 --> Ask me about our New Dual and 4 Way Blade Servers <--
