# 06-Nov-04 amo Date-of-Birth
# 13-Nov-04 amo Split off ramdisk options into linuxrc.Commands.Help.txt
# 20-Nov-04 amo Split off common mount and checking to linuxrc.common.sh
# 23-Nov-04 amo Use CFRW to debug mount CF as rw vs ro options -> linuxrc -> /etc/fstab
# 17-Mar-05 amo Added bootUSB in addition to bootCF
# 03-Sep-05 amo Added BootMsg variable
# 11-Sep-05 amo Moved some global variables into common ( CUSTOM )
# 12-Sep-05 amo New VER, RELEASE gloabl variable for Release Version
# 28-Sep-05 amo Release as 2005.0928, change $RELEASE
# 29-Sep-05 amo Use Generic Release Names ( SBM-test ) and Finalize while copying into $RELEASE
