From 34fb7a7e9d92698a721862fe0ef926d69b12a8e5 Mon Sep 17 00:00:00 2001 From: eldritch horrors Date: Sat, 9 Mar 2024 11:01:28 +0100 Subject: make the multi-node vm tests a bit more reliable without these changes the tests will very repeatably (although not very reliably) wedge in our runs. the ssh command starts, opens a sessions, does something, the session closes again, but the test does not move on. adding *just* the redirect and not the unit waits is not sufficient either, it needs both. this feels like a bug in the nixos testing framework somewhere, but digging that far is not in the cards right now.
