During omd update, Checkmk offers to delete obsolete folders and files. var/check_mk/persisted caches infrequently-gathered agent sections such as HW/SW inventory data. The update procedure would offer to wipe the persisted section cache.

The directory is now moved to the correct location and will no longer be presented for deletion during updates. If deleted, the cache is replenished automatically on the next agent check run that includes the relevant section.

This issue was introduced in Werk #18891.
