pstore.conf, pstore.conf.d — PStore configuration file
The default configuration is defined during compilation, so a
configuration file is only needed when it is necessary to deviate
from those defaults. By default, the configuration file in
/etc/systemd/ contains commented out entries
showing the defaults as a guide to the administrator. This file
can be edited to create local overrides.
When packages need to customize the configuration, they can install configuration snippets in
The main configuration file is read before any of the configuration directories, and has the lowest
precedence; entries in a file in any configuration directory override entries in the single configuration
file. Files in the
*.conf.d/ configuration subdirectories are sorted by their
filename in lexicographic order, regardless of in which of the subdirectories they reside. When multiple
files specify the same option, for options which accept just a single value, the entry in the file with
the lexicographically latest name takes precedence. For options which accept a list of values, entries
are collected as they occur in files sorted lexicographically.
/etc/ are reserved for the local administrator, who may use this
logic to override the configuration files installed by vendor packages. It is recommended to prefix all
filenames in those subdirectories with a two-digit number and a dash, to simplify the ordering of the
To disable a configuration file supplied by the vendor, the
recommended way is to place a symlink to
/dev/null in the configuration directory in
/etc/, with the same filename as the vendor

Controls whether or not files are removed from pstore after processing. Takes a boolean value. When true, a pstore file is removed from the pstore once it has been archived (either to disk or into the journal). When false, processing of pstore files occurs normally, but the files remain in the pstore. The default is true in order to maintain the pstore in a nearly empty state, so that the pstore has storage available for the next kernel error event.
The defaults for all values are listed as comments in the
/etc/systemd/pstore.conf file that
is installed by default.
