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

And for these two questions:

"- snappy_udev_setup_required() seems very brittle
  - why don't all snaps require this anyway?"

this is about to go away.

"- main() extra arguments passed through argv[] are passed to the executed
  program; is this intentional?"

yes
