The best way I found to do this was to read the source for the /lib/initcpio/{init,init_functions}
look at some of the pairs /lib/initcpio/{hooks,install}/foo for
different foo. However, you have to realize that you only have a
restricted set of binaries and shell commands available then.
Also, Arch is in the process of moving to a different initcpio system.
It's not in any of the repos yet, but is in the pipeline. I haven't
fully understood what the changes will be. I think they're getting rid
of the use of klibc.
I expect others who do know better will chime in.
