Grub config for creating my own bootable USB stick

grub.cfg

# This grub.cfg file was created by Jamie Kurtz
# Detailed instructions for use will soon be found here: http://www.jamiekurtz.com
# Simplified instructions below
# Sample grub entries... https://wiki.archlinux.org/index.php/Multiboot_USB_drive
# Inspiration from here: http://www.pendrivelinux.com/boot-multiple-iso-from-usb-via-grub2-using-linux/

# Simplified instructions...
# Make sure grub, grub-efi, and xorriso packages are installed and up-to-date
# In your terminal go to directory where want to create the USB image contents
# Run the following to create the necessary folder structure:
# $ mkdir -p multiboot/boot/{grub,iso}
# Copy ISOs into the new iso folder
# Create grub.cfg in the boot/grub folder... for example:
# $ wget https://gist.githubusercontent.com/jamiekurtz/26c46b3e594f8cdd453a/raw/grub.cfg -o multiboot/boot/grub/grub.cfg
# Create the ISO image 
# (Debian/Ubuntu) $ grub-mkrescue -o multiboot.iso multiboot
# (Fedora) $ grub2-mkrescue -o multiboot.iso multiboot
# At this point you can use VirtualBox to boot a new virtual machine using that multiboot.iso file; this is great for testing your multiboot image
# You now have two different choices for creating the USB stick itself...
# ...
# One, you can write the ISO file to a FAT32 formatted USB stick (after unmounting a USB stick that was recently inserted into the computer)
# This will completely wipe existing content on the USB stick!!
# BE SURE TO USE CORRECT DEVICE PATH BELOW!!! Your USB stick might not be /dev/sdc1 !!
# $ sudo umount /dev/sdc1
# $ sudo dd if=multiboot.iso of=/dev/sdc    # (this will take a while!)
# ...
# Or, two, if you don't want to completely wipe out your USB stick, you can do the following:
# Copy the contents of the multiboot folder (created above) to a USB stick
# Then run grub-install against the USB stick to install the grub bootloader - which will use the ISO files and grub.cfg file we just copied:
# BE SURE TO USE CORRECT DEVICE PATH BELOW!!! Your USB stick might not be /dev/sdc1 !!
# $ sudo umount /dev/sdc1
# $ mkdir -p /home/$USER/mnt/usb
# $ sudo mount /dev/sdc2 /home/$USER/mnt/usb
# $ sudo cp -r multiboot/boot /home/$USER/mnt/usb
# $ (Fedora) sudo mv /home/$USER/mnt/usb/boot/grub /home/$USER/mnt/usb/boot/grub2
# $ sudo grub-install --target=i386-pc --boot-directory=/home/$USER/mnt/usb/boot /dev/sdc
# (that would be grub2-install on Fedora)
# ...
# Once the bootable USB stick is created, you can easily add/remove ISOs and simply update the grub.cfg file (i.e. no need to do this all over again)

# Help with formatting USB stick:
# $ sudo parted /dev/sdc rm 1
# $ sudo parted /dev/sdc mklabel msdos
# $ sudo parted /dev/sdc mkpart primary 0% 100%
# $ sudo mkfs.vfat -F 32 -n MULTIBOOT /dev/sdc1
