CLI Option To Use ISO Already Downloaded

[0x004a]

Insread of: ./buildlive --root=/media/sdb1 arch mint/64/mate fedora/28
Perhaps: ./buildlive --root=/media/sdb1 arch mint/64/mate --iso=/home/user/linuxmint-mate64.iso

I've made a proof of concept in branch metaiso, and an example for arch. The code is now a little messy so I'm not going to update the code in master branch.

Usage: ./buildlive --boot /dev/sdb1 --root /dev/sdb2 --distro=arch ~/isofiles/archlinux-2020.06.01-x86_64.iso
only tested on the official archiso located in ~/isofiles

"git checkout metaiso"
"./buildlive --root /media/mint/usb1 --distro=mint/64/cinnamon /home/mint/Downloads/linuxmint-20-cinnamon-64bit.iso"
Keep getting "Usage help output" with no "--distro" option. Know you said only Arch, so perhaps that's just the problem.

Strange, I think it should give an error saying distro/.../meta not found. Yes, I only added Arch support. When you use --distro=foo, buildlive will find a file named distro/foo/meta.
I've pushed one more change for Ubuntu (Linux Mint is just an Ubuntu variant), this time it should work when you use ./buildlive --root <rootpath> --distro=ubuntu <your mint iso>.

OK, great. Will try it.
Yesterday, as you had updated Mint, used the master branch and moved a downloaded ISO into ~/isofiles.

Such a good script. Use to use MultibootUSB, but couldn't get Mint 19 installs to boot and so luckily found yours.
