NAME

6       pstore.conf, pstore.conf.d - PStore configuration file
7

SYNOPSIS

9       /etc/systemd/pstore.conf /etc/systemd/pstore.conf.d/*
10

DESCRIPTION

12       This file configures the behavior of systemd-pstore(8), a tool for
13       archiving the contents of the persistent storage filesystem, pstore[1].
14

CONFIGURATION DIRECTORIES AND PRECEDENCE

16       The default configuration is set during compilation, so configuration
17       is only needed when it is necessary to deviate from those defaults.
18       Initially, the main configuration file in /etc/systemd/ contains
19       commented out entries showing the defaults as a guide to the
20       administrator. Local overrides can be created by editing this file or
21       by creating drop-ins, as described below. Using drop-ins for local
22       configuration is recommended over modifications to the main
23       configuration file.
24
25       In addition to the "main" configuration file, drop-in configuration
26       snippets are read from /usr/lib/systemd/*.conf.d/,
27       /usr/local/lib/systemd/*.conf.d/, and /etc/systemd/*.conf.d/. Those
28       drop-ins have higher precedence and override the main configuration
29       file. Files in the *.conf.d/ configuration subdirectories are sorted by
30       their filename in lexicographic order, regardless of in which of the
31       subdirectories they reside. When multiple files specify the same
32       option, for options which accept just a single value, the entry in the
33       file sorted last takes precedence, and for options which accept a list
34       of values, entries are collected as they occur in the sorted files.
35
36       When packages need to customize the configuration, they can install
37       drop-ins under /usr/. Files in /etc/ are reserved for the local
38       administrator, who may use this logic to override the configuration
39       files installed by vendor packages. Drop-ins have to be used to
40       override package drop-ins, since the main configuration file has lower
41       precedence. It is recommended to prefix all filenames in those
42       subdirectories with a two-digit number and a dash, to simplify the
43       ordering of the files.
44
45       To disable a configuration file supplied by the vendor, the recommended
46       way is to place a symlink to /dev/null in the configuration directory
47       in /etc/, with the same filename as the vendor configuration file.

OPTIONS

50       All options are configured in the [PStore] section:
51
52       Storage=
53           Controls where to archive (i.e. copy) files from the pstore
54           filesystem. One of "none", "external", and "journal". When "none",
55           the tool exits without processing files in the pstore filesystem.
56           When "external" (the default), files are archived into
57           /var/lib/systemd/pstore/, and logged into the journal. When
58           "journal", pstore file contents are logged only in the journal.
59
60       Unlink=
61           Controls whether or not files are removed from pstore after
62           processing. Takes a boolean value. When true, a pstore file is
63           removed from the pstore once it has been archived (either to disk
64           or into the journal). When false, processing of pstore files occurs
65           normally, but the files remain in the pstore. The default is true
66           in order to maintain the pstore in a nearly empty state, so that
67           the pstore has storage available for the next kernel error event.
68
69       The defaults for all values are listed as comments in the template
70       /etc/systemd/pstore.conf file that is installed by default.
