#	050119 0.08 RPH - track down the noise we were getting on the 
#		pointing to the initrd.img and the vmlinuz and quell it
#		and also remove -rhl- specific constructs; enhance 
#		bail, sanity checking and warning structures
#	050114 0.07 RPH - add a touch of notice into the syslog
#	031024 0.06 RPH - automated run logic cleanup -- ok to 
#		delete known link files
#	030712 0.05 RPH - ks.cfg setting logic made more error 
#		resistant
#	030304 0.04 RPH - add a default ks.cfg if no custom one 
#		exists, catch umount errors
#	030220 0.03 RPH - add debugging option stanza
