Thanks Type `uname -r` to find the release number of the currently running kernel. (This number should match the version-release number of the kernel package, by not-quite-coincidence.) You can also look at /etc/grub.conf -- that's where the selection is actually made. Note that "default" starts counting from zero, so "default=0" means "select the first kernel option by default". Of course, ff the new kernel was installed recently and you haven't rebooted since then, the running kernel and the default one may be different. (Could also happen if you manually selected the other one at boot time.) Having multiple kernel packages installed won't really hurt anything, since the RPMs are carefully designed so that different versions don't conflict. However, once you've determined that a newly-installed update works fine, you can clear up space (and remove the chance of accidentally running the old one, which could be a problem in the case of a security update) by uninstalling all but the latest. -- Matthew Miller mattdm@xxxxxxxxxx <http://www.mattdm.org/> Boston University Linux ------> <http://linux.bu.edu/>
