# 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
