I'm working on setting up PXE boot server and while following some online instructions to mount the ISO and copy over everything under /mnt/install/netboot/, I noticed that a mount of ubuntu-18.04.1.0-live-server-amd64.iso is missing the install/netboot/ directory, whereas under ubuntu-16.04.5-server-amd64.iso this directory exists.
In trying to make sure I use 18.04 files, am I looking in the wrong place of the 18.04 ISO or was this whole section dropped after 16.04?
ubuntu-16.04.5:
alby@ubuntu:/$ sudo mount -o loop /var/tmp/ubuntu-16.04.5-server-amd64.iso /mnt
alby@ubuntu:/$ ls -l /mnt/install/netboot/
