Sorry Joseph and Yanis, I wasn't clear enough last night. Maybe it was too late. I'm not talking about the packages but about the file install.img. This file *IS* already on the netinstall CD and it's exactly the same as the one I had to download. I downloaded it again now in order to compare: $ md5sum /media/dvd/images/install.img ~/downloads/install.img ef3b0e14ff354c41524600c00ef44000 /media/dvd/images/install.img ef3b0e14ff354c41524600c00ef44000 /home/reinhard/downloads/install.img In order to save time and traffic, it would be nice if I could use it. There is even a menu item but it doesn't work for me. According to the error message, the installer assumed that the file install.img is on another disc. But this is not the case. It's on the netinstall CD already. > http://www.if-not-true-then-false.com/2011/centos-6-netinstall-network-installation/ > > This is a tutorial that will guide you through and points to the > correct URL for package repositories and to the correct install.img > file. Sure, but the install.img file at the package repository isn't more correct than the one on the netinstall CD. They are identical. The guy who wrote the tutorial obviously encountered the same problem but wasn't aware of the file on the CD and suggested this workaround. BTW, I got the system running. But I fear that I'll have to install it several times again because I'd like to experiment with virtual machines and LVM. It's very likely that I break something since I have no experience with them. Therefore it would save me some time if I don't have to download a file which exists on the CD already. Of course, it takes much more time to download and install the packages, but in this case, once installation is started, I can do something else meanwhile. Another thing: Even if I can use install.img from the CD, at least when I have to install packages, I have to specify an URL to a repository. Documentation proposes mirror.centos.org . Is there a reason why the installer doesn't offer the mirror URL as a default? I ask because I have only one machine and whenever the installer asks me for an URL, I have to abort and boot a system which provides a web browser in order to read the documentation, write the URL down on paper, and start the installer again. Well, I sometimes have the impression that I'm the only one in the world who doesn't have a mobile phone with a built-in web browser. :) Of course, specifying a particular server as a default isn't reasonable, it would cause too much traffic there. But given that mirror.centos.org performs load balancing, wouldn't it be possible to provide a default URL in the installer menu? It would make installation *much* more convenient. Any idea why it hasn't been done?
