From d76afbaaf40e953243da921844cddff8185324f3 Mon Sep 17 00:00:00 2001 From: Lyonel Vincent Date: Tue, 28 Jun 2022 10:22:38 +0200 Subject: [PATCH 2/2] make version check optional cf. Github PR#86 Rather than using an LSM such as SELinux to limit network access, or having to add exceptions into network monitoring, allow lshw to be built so that it doesn't do the DNS lookup to check for upstream version updates.
