loader is a BTX client as well. I will not describe it here
in detail, there is a comprehensive manpage written by Mike Smith, loader(8). The
underlying mechanisms and BTX were discussed above.
The main task for the loader is to boot the kernel. When the kernel is loaded into
memory, it is being called by the loader:
sys/boot/common/boot.c:
/* Call the exec handler from the loader matching the kernel */
module_formats[km->m_loader]->l_exec(km);
