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 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 /usr/lib/systemd/*.conf.d/ or /usr/local/lib/systemd/*.conf.d/. 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.

       Files in /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 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.
