+ help
+ When kernel code requests a module, it does so by calling
+ the "modprobe" userspace utility. This option allows you to
+ set the path where that binary is found. This can be changed
+ at runtime via the sysctl file
+ /proc/sys/kernel/modprobe. Setting this to the empty string
+ removes the kernel's ability to request modules (but
+ userspace can still load modules explicitly).
