+Estimate disk space requirements when running sos report. This can be valuable
+to prevent sosreport working dir to consume all free disk space. No plugin data
+is available at the end.
+
+Plugins will be collected sequentially, size of collected files and commands outputs
+will be calculated and the plugin files will be immediatelly deleted prior execution
+of the next plugin. This still can consume whole free disk space, though. Please note,
+size estimations may not be accurate for highly utilized systems due to changes between
+an estimate and a real execution.

Subject: [PATCH] [report] Count with sos_logs and sos_reports in
--estimate-only
Currently, we estimate just plugins' disk space and ignore sos_logs
or sos_reports directories - although they can occupy nontrivial disk
space as well.

Subject: [PATCH] [report] check for symlink before rmtree when opt
estimate-only is use
Check if the dir is also symlink before performing rmtree()
method so that unlink() method can be used instead.
