I'm bothered by the differences in their sizes. This list makes it easier to see relevant points: [root@tpMail yum.repos.d]# yum --disablerepo=* --enablerepo=centosplus info kernel.i686 | egrep 'Name|Release|Size|Repo' Name : kernel Release: 92.1.10.el5 Size : 37 M Repo : installed Name : kernel Release: 53.1.14.el5.centos.plus Size : 41 M Repo : installed Name : kernel Release: 92.1.6.el5 Size : 37 M Repo : installed Name : kernel Release: 92.1.10.el5.centos.plus Size : 16 M Repo : centosplus [root@tpMail yum.repos.d]#
One C5 kernel is 41 Mbytes, the other 16. In contrast, the other kernels are 37 Mbytes.
