From 3cbe89b12a55a0ff350d7434834f4f48227896a3 Mon Sep 17 00:00:00 2001 From: LOLi Date: Tue, 1 May 2018 05:58:29 +0200 Subject: Fix zfs incremental send remove '-o' properties When receiving an incremental send stream with intermediary snapshots zfs_receive_one() does not correctly identify the top-level dataset: consequently we restore said snapshots as if they were children datasets in the hierarchy, forcing inheritance of any property received with 'zfs send -o' and effectively removing any locally set value. The test case did not correctly verify this situation because it uses adjacent snapshots, basically testing 'zfs send -i' instead of 'zfs send -I': this commit adds an additional intermediary snapshot to the test script.
