I recently went to do a kernel upgrade on one of my linux machines,and the kernel was in /usr/src/Linux ,just where it was supposed to be. but on 3 other machines the only thing that is in /usr/src is RPM ,so when I type the command ,cd /usr/src/linux, there is no such place . I'm using Mandrake 9.1 on all of these machines. Why is the kernal in /usr/src on only one of them, and where did it put it on the other 3? I've found some 2.4.21 kernal files in the /lib and mod directories but these don't seem to be the right ones.Thanks in advance for any help. I appreciate it.
