NAME
       pstore.conf, pstore.conf.d - PStore configuration file

SYNOPSIS
       /etc/systemd/pstore.conf /etc/systemd/pstore.conf.d/*

DESCRIPTION
       This file configures the behavior of systemd-pstore(8), a tool for archiving the contents of
       the persistent storage filesystem, pstore[1].

CONFIGURATION DIRECTORIES AND PRECEDENCE
       The default configuration is set during compilation, so configuration is only needed when it
       is necessary to deviate from those defaults. Initially, the main configuration file in
       /etc/systemd/ contains commented out entries showing the defaults as a guide to the
       administrator. Local overrides can be created by editing this file or by creating drop-ins,
       as described below. Using drop-ins for local configuration is recommended over modifications
       to the main configuration file.

       In addition to the "main" configuration file, drop-in configuration snippets are read from
       /usr/lib/systemd/*.conf.d/, /usr/local/lib/systemd/*.conf.d/, and /etc/systemd/*.conf.d/.
       Those drop-ins have higher precedence and override the main 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 sorted last
       takes precedence, and for options which accept a list of values, entries are collected as
       they occur in the sorted files.

       When packages need to customize the configuration, they can install drop-ins under /usr/.
       Files in /etc/ are reserved for the local administrator, who may use this logic to override
       the configuration files installed by vendor packages. Drop-ins have to be used to override
       package drop-ins, since the main configuration file has lower precedence. It is recommended
       to prefix all filenames in those subdirectories with a two-digit number and a dash, to
       simplify the ordering of the files.

       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 configuration file.

OPTIONS
       All options are configured in the [PStore] section:

       Storage=
           Controls where to archive (i.e. copy) files from the pstore filesystem. One of "none",
           "external", and "journal". When "none", the tool exits without processing files in the
           pstore filesystem. When "external" (the default), files are archived into
           /var/lib/systemd/pstore/, and logged into the journal. When "journal", pstore file
           contents are logged only in the journal.

       Unlink=
           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 template /etc/systemd/pstore.conf
       file that is installed by default.
