there is definitely something wrong here, and it seems also in similar
code in binary_hdd...

```
LB_BOOTLOADERS="syslinux,grub-efi"
echo "${LB_BOOTLOADERS}" | while IFS="," read -r BOOTLOADER; do
	echo "bootloader: ${BOOTLOADER}"
done
```
this code always fails to split the comma separated string...

i don't know why it will not work, but i've got an alternate to replace
it with in the form:

```
for BOOTLOADER in $(echo "${LB_BOOTLOADERS}" | tr "," "\n"); do
	echo "bootloader: ${BOOTLOADER}"
done
```
