You'll need to break out your hard drive into multiple partitions, as
there are certain portions of the file system that need to be writable
such as /var and /home.  I setup systems in this manner to make them
more difficult to subvert, I'd suggestion searching for topics such as
"linux file system hardening".

When you do need to do maintenance, such as package management, you'll
need to remount the root file system as writable which will likely
require a reboot.
