From a47daa41a620c72df6a87f9dffa71f91c82fef4e Mon Sep 17 00:00:00 2001
From: Eric Thibodeau <kyron@neuralbs.com>
Date: Sat, 19 Jul 2008 21:56:01 -0400
Subject: Multiple fixes and feature additions: Fix: - stderr misredirrection
 `>2 --> >&2` - Messages now display the scriptname and not just "STATELESS...
 - Now setting domainname in the right place Features: - now a single tmpfs
 folder is mounted and folders created under that folder, ** the function
 should be easy to modify if ever one was to mount another FS than tmpfs **
 Kernel command line parameter now required, ie: rwdev=tmpfs Misc: - Cleaned
 out unused and commented code - Renamed some functions
