Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [RPM build errors:
]: [You can find build errors below this line.]
=============
[File must begin with "/": %{_sysusersdir}/testcloud.conf
]: [This error says a file path didn't start with a slash. That very often means that the included macro wasn't expanded as expected.]

Issue: All files must be specified with an absolute path, but in this case, one of the files wasn't. Most likely, the included macro %{_sysusersdir} wasn't expanded properly, most likely because it was undefined.
Resolution: Make sure that all files are specified with an absolute path. If there are macros in their path, make sure the macros are defined.
