contrib-munin/plugins/solaris/fsstat_bytes
Lars Kruse c81c20ab3b unify DIRTYCONFIG handling in shell and python plugins
The following issues were fixed:
* comparison too broad (e.g. "0" misinterpreted as "true")
* python: comparing string with number (is never equal in python)
* unwanted non-zero exitcode (compound command "&&" as last command in
  shell code block (e.g. "case" or "if" branch))
* access to unset variable (shell style issue)

=head1 NAME
fsstat_bytes - Munin plugin to monitor Solaris file system statistics
Tested with Solaris 10 and 11.
Note:
In Solaris 11, fsstat command can get stats for each non-global zones in
global zone. (see man fsstat)
In global zone, this plugin gets stats of only global zone.
In non-global zones, this plugin reports stats of the non-global zones.
