adding hooks for CentOS
forgot path info
migration to 4x
adding new install .map targets, cleanup cgi-bin targets
Fixed $mounted logic bug when initrd needs to be mounted (non ISO)
Tweaked logic on when/when not to mount, made sure $mounted reflects reality
Tweak to only do it on ISO's...
Added support for no loopmount of initrd image
Ooops, correct path directive now
Added NO_LOOPMOUNT_KS_ISO to start support for older kernels and no loopmount
