Package: ifupdown Version: 0.8.19 Severity: normal Tags: patch Hi,
we use ifupdown to configure IPoIB devices. The normal workflow is that udev loads the kernel modules for InfiniBand and activates `rdma-load-modules@infiniband.service`, which loads `ib_ipoib`. Then `networking.service` runs afterwards and configures the IPoIB devices. We had one system where `networking.service` was started before `rdma-load-modules@infiniband.service` and therefore failed to configure the IPoIB devices: ``` $ zgrep --color '\(RDMA\|Reached target\|Raise network\)' /var/log/syslog.1.gz | head -n 23 Jun 18 21:50:19 systemd[1]: Started Load RDMA modules from /etc/rdma/modules/srp_daemon.conf.

So I suggest to let `ifupdown-pre.service` declare to run before `network-pre.target`. That way it is ensured that `rdma-load-modules@infiniband.service` is activated before `network-pre.target` is reached. As alternative, `rdma-load-modules@.service` could declare to run before `networking.service` in addition to `networking-pre.target`. -- Benjamin Drung DevOps Engineer and Debian & Ubuntu Developer Platform Integration (IONOS Cloud) 1&1 IONOS SE | Greifswalder Str. 207 | 10405 Berlin | Germany E-mail: benjamin.dr...@cloud.ionos.com | Web: www.ionos.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Dr. Christian Böing, Hüseyin Dogan, Dr. Martin Endreß, Hans-Henning Kettler, Arthur Mai, Matthias Steinberg, Achim Weiß Aufsichtsratsvorsitzender: Markus Kadelke Member of United Internet
