PSTORE.CONF(5)                 pstore.conf                PSTORE.CONF(5)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       The default configuration is set during compilation, so
       configuration is only needed when it is necessary to deviate from
       those defaults. The main configuration file is either in
       /usr/lib/systemd/ or /etc/systemd/ and contains commented out
       entries showing the defaults as a guide to the administrator.
       Local overrides can be created by creating drop-ins, as described
       below. The main configuration file can also be edited for this
       purpose (or a copy in /etc/ if it's shipped in /usr/) however
       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. This
       also defined a concept of drop-in priority to allow distributions
       to ship drop-ins within a specific range lower than the range
       used by users. This should lower the risk of package drop-ins
       overriding accidentally drop-ins defined by users.

       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         top

       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.

           Added in version 243.

       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.

           Added in version 243.

       The defaults for all values are listed as comments in the
       template /etc/systemd/pstore.conf file that is installed by
       default.
