build.sh script fails when generating the ISO image

[angel-devicente]

Hello,

I'm trying to use your ./build.sh script following the README instructions, but when it gets to the image generation step I get the following error:

+ sudo genisoimage -r -V CUSTOM xenial 20220630 - amd64 -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -p vagrant <on host ubuntu2\
004.localdomain> -A CUSTOM xenial 20220630 - amd64 -m filesystem.squashfs -o ../CUSTOM-xenial-20220630-amd64.iso.tmp .
I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage: Uh oh, I cant find the boot catalog directory 'isolinux'!

All good if adding cd image

# Creating the ISO image from the tree                                                                                                                                                                 
cd image
