Arguments position not flexible: "create containerid --bundle dir"

[alban]

When trying to run crun with arguments in the wrong order, it does not work but the error message is not so clear:

$ ./crun create containerid --bundle /home/alban/oci/c1
2018-03-09T17:54:33.000102555Z: error loading config.json

When using the correct order (./crun create --bundle /home/alban/oci/c1 containerid), it works.

I found this issue when trying to run the OCI runtime validation tests.

runtime-tools seems to do the wrong thing here (I just filed opencontainers/runtime-tools#600) according to the CLI spec. But maybe the crun arguments parsing could be made more flexible, or improve the error message somehow?

thanks for the report. Indeed that is confusing and crun must give a better error message, I've pushed this commit to address it:

Please feel free to reopen the issue if that is not good enough.
