+#
+# The systemd-pstore.service(1) archives the contents of /sys/fs/pstore
+# upon boot so that there is room for a subsequent dump. This service
+# is enabled with:
+#  systemctl enable systemd-pstore
+#
+# With the service enabled, the kernel still needs to be configured
+# to write data into the pstore. The kernel has two parameters,
+# crash_kexec_post_notifiers and printk.always_kmsg_dump, that
+# control writes into pstore.
+#
+# The crash_kexec_post_notifiers parameter enables the kernel to write
+# dmesg (including stack trace) into pstore upon a panic even if kdump
+# is loaded, only needed if you want to use pstore with kdump. Without
+# this parameter, kdump could block writing to pstore for stability
+# reason. Note this increases the risk of kdump failure even if pstore
+# is not available.
+#
+# The printk.always_kmsg_dump parameter enables the kernel to write dmesg
+# upon a normal shutdown (shutdown, reboot, halt).
+#
+# To configure the kernel parameters, uncomment the appropriate
+# lines below. The value written is either 'Y' to enable the
+# kernel parameter, or 'N' to disable the kernel parameter.
+#
+# After making a change to this file, do:
+#  systemd-tmpfiles --create path/to/tmpfiles.d/systemd-pstore.conf
+#
+# These changes are automatically applied on future re-boots.
