Hello, I have a FC6 system (with no updates). When I do 'uname -r', I get "2.6.18-1.2798.fc6", the standard kernel that comes with the original FC6. I have been reading and following the instructions in the link "http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/RELEASE-NOTES-en_US.html" section 8.6, to get the full kernel source to the above kernel. One of the instructions says: yumdownloader -e core-source -e updates-source --source kernel Can someone please tell me what the options - core-source and updates-source do? I have done some googling, read man pages, but to no luck. Any explanation or pointers to web pages that explain these options would be appreciated. Will the option "updates-source" update my kernel version. Thank you, Ahmed. ____________________________________________________________________________________ Be a PS3 game guru.
