+# 1 - Conservative address space randomization makes the addresses of
+#     mmap base and VDSO page randomized. This, among other things,
+#     implies that shared libraries will be loaded to random addresses.
+#     Also for PIE binaries, the location of code start is randomized.
+# 2 - This includes all the features that Conservative randomization
+#     provides. In addition to that, also start of the brk area is randomized.
+#     There a few legacy applications out there (such as some ancient
+#     versions of libc.so.5 from 1996) that assume that brk area starts
+#     just after the end of the code+bss. These applications break when
+#     start of the brk area is randomized. There are however no known
+#     non-legacy applications that would be broken this way, so for most
+#     systems it is safe to choose Full randomization.
