[Users] rpms signed - why not?

I was setting up our spacewalk repo for ovirt due to auto provisioning engine and node based on centos distro, but I was surprised that you can't sign with gpg key your rpms, instead gluster rpms is signed with key id 89ccae8b available on her site Why you don't sign your rpms? e.g: $ wget http://resources.ovirt.org/releases/3.3.2/rpm/EL/6/noarch/ovirt-engine-3.... $ rpm -K -v ovirt-engine-3.3.2-1.el6.noarch.rpm ovirt-engine-3.3.2-1.el6.noarch.rpm: Digest SHA1 header: OK (f8cf0a7592ae3d8d298813cf61ec8b4e2ad6b6f6) MD5 digest: OK (bc4b66e0791b3ef5dd8e9b49828ad7d8) instead gluster rpms: $ wget http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-6... $ rpm -K -v glusterfs-3.4.2-1.el6.x86_64.rpm glusterfs-3.4.2-1.el6.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 89ccae8b: NOKEY Header SHA1 digest: OK (e71040f320da087e6e9012102e0e59f134259d2a) V4 RSA/SHA1 Signature, key ID 89ccae8b: NOKEY MD5 digest: OK (01e72fe3ed97ba849327cafe43ca5d45) best regards a -- Amedeo Salvati RHC{DS,E,VA} - LPIC-3 - UCP - NCLA 11 email: amedeo(a)oscert.net email: amedeo(a)linux.com http://plugcomputing.it/redhatcert.php http://plugcomputing.it/lpicert.php
