This list makes it easier to see relevant points: [root at 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 at tpMail yum.repos.d]# One C5 kernel is 41 Mbytes, the other 16. In contrast, the other kernels are 37 Mbytes. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-)
