important data structures:
%FAI::commands : initialized in Init.pm
Holds all commands as well as their dependencies and
post-execution status. &FAI::order_commands is used on it to set
the correct order of commands and resolve the dependencies.
Commands are added to the structure by using the
FAI::push_command(COMMAND, PRE, POST) subroutine.
