# 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
|
|
# 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.
