From 00934bb90865b6ccd3b226c7d495adbf4dabc9da Mon Sep 17 00:00:00 2001 From: aszlig Date: Mon, 14 Dec 2015 17:39:55 +0100 Subject: [PATCH] nixos/tests: Revert setting min_free_kbytes This reverts commit 02b568414d509b5d06dbd95bcc0868d487ed359e. With a5bc11f and 6353f58 in place, we really don't need this anymore. After running about 500 VM tests on my Hydra, it still didn't improve very much.
