There will be documentation if you write it. :)

It goes something like this (this lacks any kind of detail mind you,
look at the code for that), the initial file-system is the first part
that gets started, then exec (look at the menu.lst for GRUB). These
two get started by the kernel.

The initial file-system translator then runs init (see
[hurd]/libdiskfs/boot-start.c:diskfs_start_bootstrap()).  From there
init starts proc, auth and as it's final step, /libexec/runsystem (see
[hurd]/init/init.c).  When /libexec/runsystem has finished, you have
an fully working system.
