fedora FC3からFC4への更新 - external storage 1

[root@game0 tmp]# yum update

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

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

warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 1ac70ce6
public key not available for //var/cache/yum/extras/packages/skkdic-20050614-1.fc4.noarch.rpm

GPG public keyをインポートして、事なきを得ました。
# rpm --import /usr/share/doc/fedora-release-*/RPM-GPG-KEY*
