Does it mean that if I installed CentOS 4.0, I have to do a yum upgrade
on the 4.0 tree in order to have the last version of all installed
packages then a yum upgrade on the 4.1 tree ?
Or is it possible to do a yum upgrade directly on the 4.1 tree and it
will upgrade all the installed packages ?
If it is the first question which list the correct steps, how are made
the updates if I install after a period a package from my CentOS 4.0 iso
and then do a yum upgrade on the 4.1 tree? (Perhaps that there was an
update in the 4.0 updates tree. Or do I miss something?)
One more question : Is it better to do yum update or yum upgrade if I
want only the already installed packages to be updated ?
Thank you for your help,
Jean LEE.
