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


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


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


       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.


       All options are configured in the [PStore] section:

           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.

           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.
