I don't know more than the source code :)

hurd/$ git grep -i TASK_BOOTSTRAP_PORT .
libdiskfs/boot-start.c:  err = task_set_special_port (diskfs_exec_server_task, 
TASK_BOOTSTRAP_PORT, right);

glibc/$ git grep -i TASK_BOOTSTRAP_PORT .
hurd/hurdinit.c:  __task_set_special_port (__mach_task_self (), 
TASK_BOOTSTRAP_PORT,
hurd/hurdstartup.c:  if (err = __task_get_special_port (__mach_task_self (), 
TASK_BOOTSTRAP_PORT,
