Also, the warning appears a second time at the end of the install process.

Successfully installed the Netdata Agent.

The following non-fatal warnings or errors were encountered:

  - Cannot find usable OS release information. Native packages will not be available for this install.

Mind the poor wording, but I don't meant redundant because it appears twice.

The user requested a '--static-only' install, thus he does not want native packages at all.
Only if the user does not specify '--static-only' the waning makes sense, but since he already asked for static-only, it doesn't.

makes sense?
