Checkmk Werk 15698: mk_filestats: Crash on baking with "Deploy without configuration"

ID: 15698 Title: mk_filestats: Crash on baking with "Deploy without configuration" Component: agents Level: 1 Class: Bug fix Version: 2.3.0b1 This is a regression that came with Checkmk 2.1.0p26/Werk #15458. When configuring the agent ruleset <i>Count, size and age of files - mk_filestat (Linux/Solaris)</i> and selecting "Deploy the Filestats plugin without configuration", previously, the agent bakery did crash with a message containing C+: cmk.utils.exceptions.MKGeneralException: Error running automation call bake-agents (exit code 2), error: ‘bool’ object is not iterable C-: As a consequence of the fix, the structure of the ruleset had to be adapted to actually support rule merging.<br> See the inline help of the ruleset for more details.<br> However, existing rules will be auto-migrated to the new structure.
