[CentOS-mirror] major/minor version in tree

Hi - I apologize for the newbie question. I did some searching of the archives and couldn't find it, but there wasn't an actual search box that i found.

I am creating a local mirror for our servers, and am only creating the trees that we need. Currently we only need version 5.2. Do I need to create the tree for 5 as well as 5.2? For example, so far I have created the directories:

/var/www/html/centos/5.2/os/i386 /var/www/html/centos/5.2/updates/i386 /var/www/html/centos/5.2/os/x86_64 /var/www/html/centos/5.2/updates/x86_64

and I'm wondering whether I also need to create:

/var/www/html/centos/5/os/i386 /var/www/html/centos/5/updates/i386 /var/www/html/centos/5/os/x86_64 /var/www/html/centos/5/updates/x86_64

Thanks for your help, Maria
