hey friends, I have some questions regarding updating of the Fedora Core or any other Red hat Product. a) What is the difference between yum and up2date? and which one is the best tool for updating the system. b) If i do "yum update" .Does the yum installs the packages or it just download the packages and one has to install the packages/rpms manually? Where does the yum stores the downloaded rpms/packages? c) If I use the up2date for updating my system it download the rpms under /var/spool/up2date directory.One has to manually install the rpms downloaded by up2date if not specified while downloading "to install the packages" and there are some .hdr files also.One should delete these .hdr /rpms if the system is updated to the latest updates available. d) When we click on the updated rpms downloaded in the /var/spool/up2date folder sometimes they ask for fedora cd I know it is due to dependency problem.Now suppose there is no cd-rom attached to the system.But there is a cdrom available through nfs .One should do this or not mount -t nfs machine_name:/mnt/cdrom /mnt/cdrom Means mounting the remote cdrom directory onto the local directory.If still the system asks for cd while updating the system then which is the best way to resolve that conflict.
