From b880be1ae9d5fc2190d4e2178626776aecfa5243 Mon Sep 17 00:00:00 2001
From: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>

Subject: Implement mount hook function in archiso hook.

Next version of mkinitcpio > 0.6.2 implements mount hook functionality.
So can avoid skipping normal flow of main init script, and removing common
end code with it.
