Would someone post a yum.conf for me? Because seem that the yum in FC3 is changed and I don't know how to do because I am still using FC2's yum.conf. Is it still work ??
yum configuration has changed for FC3. There is a generic /etc/yum.conf file that you use to set options that will apply to all repositories (like the "main" section in FC2 yum.conf), and then separate files in the /etc/yum.repos.d for each repository. So, to convert from FC2, split your existing yum.conf into separate files for each repository and put the files in directory /etc/yum.repos.d. Then rename /etc/yum.conf.rpmnew to /etc/yum.conf so set up the defaults. Change distroverpkg in the resulting yum.conf from redhat-release to fedora-release. Everything should then work as before.
