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. The
main configuration file is loaded from one of the listed directories in
order of priority, only the first file found is used: /etc/systemd/,
/run/systemd/, /usr/local/lib/systemd/ [2], /usr/lib/systemd/. The
vendor version of the file contains commented out entries showing the
defaults as a guide to the administrator. Local overrides can also 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 is
shipped under /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. This also defines a concept of drop-in priorities to allow OS
vendors 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. It is recommended to use the
range 10-40 for drop-ins in /usr/ and the range 60-90 for drop-ins in
/etc/ and /run/, to make sure that local and transient drop-ins take
priority over drop-ins shipped by the OS vendor.
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.
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.

at all times. If /usr/local/ is a separate partition, it may not be
available during early boot, and must not be used for configuration.
