[libvirt] [PATCH] Revert "daemon: use socket activation with systemd"

This reverts commit 1e9808d3a1e00a7121bae8b163d9c42d441d2ca8. We shouldn't advertise libvirtd.socket activation, since currently it means VM/network/... autostart won't work as expected. We tried to find a middle ground by installing the config file without an [Install] section, since systemd won't allow .socket to be enabled without one... or at least it did do that; presently on f24 it allows activating the socket quite happily. This also caused user confusion[1] Just remove the socket file. I've filed a new RFE to track coming up with a solution to the autostart problem[2], we can point users at that if there's more confusion: [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1279348 [2]: https://bugzilla.redhat.com/show_bug.cgi?id=1326136 --- .gitignore | 1 - daemon/Makefile.am | 14 ++------------ daemon/libvirtd.conf | 5 ----- daemon/libvirtd.service.in | 5 +++++ daemon/libvirtd.socket.in | 11 ----------- libvirt.spec.in | 7 ++----- 6 files changed, 9 insertions(+), 34 deletions(-) delete mode 100644 daemon/libvirtd.socket.in diff --git a/.gitignore b/.gitignore index 0d12c5c..381db69 100644 --- a/.gitignore +++ b/.gitignore @@ -63,7 +63,6 @@ /daemon/libvirtd.pod /daemon/libvirtd.policy /daemon/libvirtd.service -/daemon/libvirtd.socket /daemon/test_libvirtd.aug /docs/aclperms.htmlinc /docs/apibuild.py.stamp diff --git a/daemon/Makefile.am b/daemon/Makefile.am index 2dbe81b..fc6fd95 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -59,7 +59,6 @@ EXTRA_DIST = \ libvirt.rules \ libvirtd.sasl \ libvirtd.service.in \ - libvirtd.socket.in \ libvirtd.sysconf \ libvirtd.sysctl \ libvirtd.aug \ @@ -446,18 +445,15 @@ endif !
