Well, the kernel invokes /sbin/init once it's mounted the root partition;
you could start from there, reading the man pages on init and inittab.
Also, once you've read a small bit of that, /etc/init.d/README is _very_
useful in figuring out the Debian way of doing things with regard to
system startup.

Well, this satisfies both criteria, though it may be a bit briefer than
you want: (assuming you have installed mandb, perl, and netstd, and
assuming that your default shell is bash)
telnet localhost | tee foo.log
<login as normal>
<hit tab twice at the prompt and answer "y" when asked>
logout
Now, edit foo.log with your favorite editor so that all it contains are
those lines with those various possible commands. Then:
(these two lines should all be typed as one big long line)
perl -ne 'while ($a = m/[^\s]+/g) {print "$&\n";}' foo.log |
sort | xargs man -f > commands.log
This is a bit of a summary - I only wish that there were an easier way to
generate the initial list with the telnet...

Oh, and read the bash and bash-builtins man pages too.
