But only if it can be booted in the first place. I have two machines
that can use USB, but whose BIOS cannot boot from USB. The machines
are older but still healthy and capable. They generate bugs because
developers (kernel, X11) tend to slight such hardware unnecessarily.
So please make explicit the recipe for booting the kernel from CD but
switching as soon as possible to USB root, and freeing the CD drive
for use by the running system.
