So can I just copy the RPM from my 5.3 to my 5.4 and all will be good? No need to makerepo or anything? [root at alan centos]# find . -name yum-prio\* ./5.3/os/i386/CentOS/yum-priorities-1.1.16-13.el5.centos.noarch.rpm ./5.3/os/x86_64/CentOS/yum-priorities-1.1.16-13.el5.centos.noarch.rpm Just copy those to the same spot under 5.4? -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"
