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 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.
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removed from the pstore once it has been archived (either to disk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.
