+Subject: [PATCH] ceph-osd postinst: do not always reload all sysctl settings
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ceph-osd installs a /etc/sysctl.d/30-ceph-osd.conf with custom sysctl
+settings. Currently, in order to apply them, ceph-osd postinst always
+restarts procps. However, this triggers a reload of *all* sysctl
+settings when installing or upgrading the ceph-osd package. This may
+needlessly reset unrelated settings manually changed by the user.
+
+To avoid this, invoke /lib/systemd/systemd-sysctl manually to apply
+the custom sysctl settings only, and only do so on fresh installs of
+the package.
+
+If 30-ceph-osd.conf is changed in the future, the ceph-osd postinst
+will need to be adjusted to apply the sysctl settings on upgrade too.
+
