# 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, and
# 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
# line(s) 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.
