描述

The warning introduced by 971808ec9f62bc3f8e0347ebace6a19429d4e61d about data duplication is not accurate. I did a write-up about why the rule of thumb provided is not accurate:

@FransUrbo I do not really want to have people spreading FUD quote the man page when I try to explain how things actually work. This message should be amended for accuracy.

研究方向
The issue references a HN comment explaining why the deduplication warning is inaccurate. The warning was introduced in commit 971808ec9f62bc3f8e0347ebace6a19429d4e61d. To resolve, locate that warning message in the codebase, read the HN link, and amend the message to be accurate. No assignee or PR exists. The issue is old and may require understanding of deduplication internals.
