Ahh, the (an) obvious (finally ;-) alternate solution is to incorporate the
luks and mount commands directly in the c helper program, as that at least
avoids the confusion (to me) of having both a script and a c program for each
partititon (and I could consider "parameterizing" the partitions).
E.g., in my (typical) c program, instead of
setuid( 0 );
system( "<bash_script_filename>" );
do
setuid( 0 );
system( "/sbin/cryptsetup luksOpen /dev/sd<ann> <luks_device_name> " );
system( "/bin/mount /dev/mapper/<luks_device_name> <mount_point>" );
