Hi Karanbir: I suggest it's better to have releasever=4.3 work for the new mirrorlist, since releasever=4.3 is working with baseurl, i.e baseurl=http://mirror.centos.org/centos/4.3/os/i386/ It's better to be consistent that releasever=4.3 works with new mirrorlist, i.e. mirrorlist=http://mirrorlist.centos.org/?release=4.3&arch=i386&repo=os Thanks. -- Steven
