It configures qemu to use the tty it was started in for IO (as opposed to
opening a separate graphical window). This enables copy-pasting and
scrollback. Exit qemu with C-a x.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Also add the
'-nographic' qemu argument when called with #:graphic? #false.
* guix/scripts/system.scm (system-derivation-for-action): Propagate
the #:graphic? keyword arg.
(perform-action): Add and propagate the #:graphic? keyword arg.
(show-help): Add --no-graphic CLI arg.
(%options): Process the new --no-graphic CLI arg.
(process-action): Feed in the CLI arg through the #:graphic? keyword arg.
