Code review comment for lp:~jdstrand/snap-confine/ubuntu-core-launcher.nnp-off

The seccomp_load_filters() error handling is still very confusing since there are a mix of die()'s and non-zero return values which ultimately end in a die(). If seccomp_load_filters() is going to internally call die() upon error in some conditions, it should be changed to have a void return and simply call die() in all error conditions. I believe that was what Seth was suggesting, as well.
