Couple days ago I decided to use netinstall CD to install CentOS but got somewhat surprised by the “URL Setup” step as I didn’t expect to enter full URL containing installation image.

centos_url_setup

URL for 32-bit installation image:

http://mirror.centos.org/centos/6/os/i386/

URL for 64-bit installation image:

http://mirror.centos.org/centos/6/os/x86_64/

URL path is easy to remember and can be used with any other mirror.
