36
- * FreeBSD has this rather strange "feature" of its design.
37
- * At some point in its evolution, FreeBSD started to rely
38
- * externally on private/static/debug internal symbol information.
39
- * That is, some of the interfaces that software uses to access
40
- * and work with the FreeBSD kernel are made available not
41
- * via the shared library symbol information (the .DYNAMIC section)
42
- * but rather the debug symbols.  This means that any symbol, not
43
- * just publicly defined symbols can be (and are) used by system
44
- * tools to make the system work.  (such as top, swapinfo, swapon,
45
- * etc)
46
- *
47
- * Even worse, however, is the fact that standard ELF loaders do
48
- * not know how to load the symbols since they are not within
49
- * an ELF PT_LOAD section.  The kernel needs these symbols to
50
- * operate so the following changes/additions to the boot
51
- * loading of EtherBoot have been made to get the kernel to load.
52
- * All of the changes are within IMAGE_FREEBSD such that the
53
- * extra/changed code only compiles when FREEBSD support is
54
- * enabled.
