Fedora 20/21, delete old system kernel, fedora Kernel

The kernel update speed of the Fedora system is very fast, which often leads to many versions during startup. If you do not clean up for a long time, the/boot may be fully occupied. The recent new Fedora 21 is even more likely to frequently upgrade the kernel. Therefore, the old kernel deletion method record is as follows:
