Probing

--probe (shorten -p) gives you details about ISO boot capabilities and list available USB drives.

Using --assume-yes + --autoselect

--assume-yes (shorten -y) bypass prompting the user for overwritting USB device, and --autoselect (shorten -a) allow automatic selection of USB device when exactly one device is connected in combination with --assume-yes.

No-USB device failure

In the below example, the selected device with --device (shorten -d) flag is not connected through USB and bootiso fails.

Distros tweaks

• On Fedora, set BOOTISO_SYSLINUX_LIB_ROOT environment to /usr/share/syslinux.
• Take a look at the by-distribution dependency table to make sure you have all required dependencies installed.
