From a0dd209763f9e67054ee322a2dfd52bccf345c2e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Thu, 12 Oct 2017 22:34:54 +0200 Subject: [PATCH] units: replace remote-cryptsetup-pre.target with remote-fs-pre.target remote-cryptsetup-pre.target was designed as an active unit (that pulls in network-online.target), the opposite of remote-fs-pre.target (a passive unit, with individual provider services ordering itself before it and pulling it in, for example iscsi.service and nfs-client.target). To make remote-cryptsetup-pre.target really work, those services should be ordered before it too. But this would require updates to all those services, not just changes from systemd side. But the requirements for remote-fs-pre.target and remote-cryptset-pre.target are fairly similar (e.g. iscsi devices can certainly be used for both), so let's reuse remote-fs-pre.target also for remote cryptsetup units. This loses a bit of flexibility, but does away with the requirement for various provider services to know about remote-cryptsetup-pre.target. --- man/crypttab.xml | 2 +- man/systemd.special.xml | 20 ++++---------------- src/cryptsetup/cryptsetup-generator.c | 2 +- units/meson.build | 1 - units/remote-cryptsetup-pre.target | 15 --------------- units/remote-cryptsetup.target | 2 +- 6 files changed, 7 insertions(+), 35 deletions(-) delete mode 100644 units/remote-cryptsetup-pre.target diff --git a/man/crypttab.xml b/man/crypttab.xml index ac7d55271c..caed04836e 100644 --- a/man/crypttab.xml +++ b/man/crypttab.xml @@ -198,7 +198,7 @@ started after the network is available, similarly to systemd.mount5 units marked with .
