Just a question , what if i have usb flash drive 8GB can i print "mylivecd name.iso" and don't care about size because i want to burn the iso file on usb flash drive not DVD ? is that possible ? and never get the problem with size like "Argument "" isn't numeric in division (/) at /usr/sbin/mylivecd line 248" ?
If you want to write the iso to a flash drive instead of a DVD, you should of course not use K3b. Use Just 18's live USB creator instead. If it's installed by default, you'll find it in the main menu ("Applications"->"More Applications"->"Configuration"->"PCLinuxOS Live USB Creator"). If it's not installed you'll find it in Synaptic. I don't know whether there's a limit to the size of the isos it can handle, but if there is I'm certain it's high enough.
No limit I came across, thankfully.
The limit is with creating the ISO ..... size limitations apply there.
But, I have remastered a huge install, specifying a working directory with the mylivecd option (which does not automatically get deleted) and after it fails to create the ISO (due to size limitation), I have used the files in the working directory to create a liveUSB install on a prepared partition of a flash stick.
I did several about 11GB, and one about 15GB ...... my flash stick was 16GB max. (EDIT
: Those are compressed sizes
So there is a way to have a huge live USB that cannot presently be used to create an ISO file.
