9 You just slow the attack a little bit by removing the compiler. The attacker will probably use
10 statically linked binaries, or compile somewhere else. Most rootkits do not depend on external
11 libraries, neither, except for kernel modules, of course, that depend on the kernel's source.

13 But, of course, if they got access to the box, then the compiler is the least of your problems at
14 that time, but I have to admit that the "slowing the attacker down" is an extra layer of protection.
15 It provides the sysadmins/users/monitoring software more time to detect the breach.
