##
## File:  mkrr_fs_gnu
##
## This is sample shell code for creating ISO9660 CD 
## images, with Rock Ridge extensions, using the GNU 
## software application, mkisofs.
##
## If using this script with mkcd, this file must be linked 
## to /usr/sbin/mkrr_fs.  For example:
##    ln -s /usr/samples/oem_cdwriters/mkrr_fs_gnu /usr/sbin/mkrr_fs
##
## Parameters:  output_file file_system
##                use_dvd_flag (any non-zero parameter)
##                output_file (i.e. /mkcd/cd_images/cd_image_67890)
##                file_system (i.e. /mkcd/cd_fs/67890)
##
## Return Codes:  0 for successful
##                1 for unsuccessful
##

##  **NOTE: mkisofs v1.12 must be installed to use the "-U"
##          flag.  This will create untranslated directory
##          and file names (non-ISO9660), but will allow
##          proper booting on CHRP systems.
