From 699b526c4738afed15995cb269ded76cbaca782b Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Wed, 12 Dec 2018 12:14:39 +0100 Subject: [PATCH] mkswap: use dd(1) in example rather than fallocate(1) The man page warns against fallocate on some filesystems and recommends dd(1) as the most portable solution. So, let's use dd(1) also in the example used in the same man page.
