hi, i'm just accidentally recognize that on rhel-6: ---------------------------------------------- # rpm -qpi rhnsd-4.9.3-2.el6.x86_64.rpm warning: rhnsd-4.9.3-2.el6.x86_64.rpm: Header V3 RSA/SHA256 signature: NOKEY, key ID f21541eb Name : rhnsd Relocations: (not relocatable) Version : 4.9.3 Vendor: Red Hat, Inc.

(i run ths command on a centos system) so if centos just rebuild the same src.rpm then do not need to modify the package and the spec! (ok this pacakge won't be included in centos anyway, just an example) since in that case the buildhost and vendor changed because of the build system and the summary and other part will change "automagically" even if the spec file contains _hard coded_ "Red Hat". this can save same useless work.. just my 2c. -- Levente "Si vis pacem para bellum!"
