Incorrect error when directory does not exist

[ThePrez]

When running chroot_setup when a directory in the tree does not exist, it gives the following error:

ERROR: [CHROOT DIRECTORY] Must begin with /QOpenSys/...

It really should give a better error (or maybe just work). I suspect we really just need the appropriate logic here, to handle the file not missing (readlink is just failing in the current implementation, so the variable is empty)

ibmichroot/chroot_setup.sh

Line 388 in 2a55b64

TEMP_DIR=$(/QOpenSys/pkgs/bin/readlink -f $1) #this is done because the arg may be a relative path name. Needs to be done, therefore, before any 'cd'

Looks like we ensure the chroot dir must begin with /QOpenSys before even attempting to create it later down the line.

ibmichroot/chroot_setup.sh

Lines 394 to 413 in 2a55b64

	echo "$TEMP_DIR" | grep -iE '^[/]+QOpenSys/.+'
	if [ $? -ne 0 ]; then
	printf "\nERROR: [CHROOT DIRECTORY] Must begin with /QOpenSys/...\n"
	print_usage
	exit -2;
	fi
	CHROOT_DIR=$TEMP_DIR
	# Check if the specified Dir Already Exists
	if [ ! -d "$CHROOT_DIR" ]; then
	echo "$CHROOT_DIR Does not Exist"
	mkdir -p "$CHROOT_DIR"
	#check if mkdir failed
	if [ $? -ne 0 ]; then
	echo "***$CHROOT_DIR creation failed!***"
	exit -3;
	fi
	echo "+++$CHROOT_DIR creation was successful!+++"

. We could check if the directory even exists first then error out before ensuring the the path of the chroot dir begins with /QOpenSys
