FirstYum

FedoraCore3 で最初にyum を実行すると :

 [root@colinux jack]# yum install svn

 You have enabled checking of packages via GPG keys. This is a good thing. 
 However, you do not have any GPG public keys installed. You need to download
 the keys for packages you wish to install and install them.
 You can do that by running the command:
    rpm --import public.gpg.key
 For more information contact your distribution or package provider.

といわれます。yum.conf で gpgcheck=0 で disable にすることもできますが、:

 rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora

で、インスコできるので、せっかくなので enable にしときます。
