"I believe that problem was introduced in 9114053378be00cd4d94d849ffc07903f407153e commit and it is a bug right now. We shouldn't use inst.repo=cdrom:LABEL='blah' for installation from usb stick, cause usb stick have different way to load than cdrom one. inst.repo=hd:device:/path and inst.ks=hd:device:/path should be used instead as it was in previous versions of Fuel and as it said in official documentation [0]. Feel free to fill a bug about it if you think similar way and assign it to me."
