Comment 2 for bug 221894

I have tested and found the same problem.

Given that nobody without knowledge of undocumented parameters can use ltsp-build-client for it's intended purpose, I believe this to be a bug, and I believe it should remain a bug until either:
1) ltsp-build-client scripts no longer depend on universe packages
or
2) ltsp-build-client gives informational warning telling users the build will fail without the parameter, and why
or
3) The package the ltsp-build-client scripts are a member of moves to universe and, by default, enables the universe component in the client environment
