I don't know the reason from the tip of my head. To investigate, we need
to take a closer look at the ISO-creation step. It is performed as part
of the 'build_boot_image' function of the run script (NOVA-specific
implementation at base-nova/run/env line 85), which calls the
platform-independent function 'create_iso_image_from_run_dir' (located
at tool/run line 419). The run tool, in turn, invokes the external
utility tool/create_iso with the following arguments:

  <genode-dir>/tool/create_iso iso ISO=<build-dir>/var/run/seoul-fancy

The create_iso utility is actually a Makefile that uses the mkisofs
command. Please take a look inside tool/create_iso to see the
command-line options or, even better, remove the '@' character from line
40 to make the command arguments visible when create_iso is invoked the
next time, and retry the create_iso step. For reference, when it works
as it should, the output looks as follows:

  mkisofs     -f -l -R -hide-rr-moved -jcharset utf-8 -no-emul-boot
-boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -o
/open/build/genode/nova_x86_64/var/run/seoul-fancy.iso
/open/build/genode/nova_x86_64/var/run/seoul-fancy
  Warning: -follow-links does not always work correctly; be careful.
  Size of boot image is 4 sectors -> No emulation

The reason for the failure might be even unrelated to mkisofs. For
example, the create_iso tool relies on binutils installed on your
machine as it invokes the strip command. Or maybe there is not just not
enough disk space left?

Best regards
Norman
