Even then, the kernel could be modified to lie about the contents of the
files.  You really can't trust anything.

I highly recommend having your own kickstart script and/or postinstall
script.  There should be a little script that installs all of the
packages that you need and checks out config files from a Git
repository.  This makes it really easy to recover from problems, whether
they come from hacking, hardware failure, or mistakes.
