From 7b9c68766d513260d5262d5782b46384834cdb33 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Mon, 17 Jun 2019 08:43:45 +0200 Subject: Add '--no-net' convenience flag This flag * Disables substituters. * Sets the tarball-ttl to infinity (ensuring e.g. that the flake registry and any downloaded flakes are considered current). * Disables retrying downloads and sets the connection timeout to the minimum. (So it doesn't completely disable downloads at the moment.)
