From 834063202a16592e1ef5c3a9fbd04ca5f1df3ed0 Mon Sep 17 00:00:00 2001 From: Alan Somers Date: Wed, 14 Feb 2018 20:26:09 +0000 Subject: [PATCH] gpart: append partition name to the underlying provider's physical path If the underlying provider's physical path is null, then the gpart device's physical path will be, too. Otherwise, it will append the partition name, such as "/p1" or "/s1/a". This will make gpart work better with zfsd(8).
