10
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
16 The default configuration is defined during compilation, so a
17 configuration file is only needed when it is necessary to deviate from
18 those defaults. By default, the configuration file in /etc/systemd/
19 contains commented out entries showing the defaults as a guide to the
20 administrator. This file can be edited to create local overrides.
21 When packages need to customize the configuration, they can install
23 configuration snippets in /usr/lib/systemd/*.conf.d/ or
24 /usr/local/lib/systemd/*.conf.d/. The main configuration file is read
25 before any of the configuration directories, and has the lowest
26 precedence; entries in a file in any configuration directory override
27 entries in the single configuration file. Files in the *.conf.d/
28 configuration subdirectories are sorted by their filename in
29 lexicographic order, regardless of in which of the subdirectories they
30 reside. When multiple files specify the same option, for options which
31 accept just a single value, the entry in the file with the
32 lexicographically latest name takes precedence. For options which
33 accept a list of values, entries are collected as they occur in files
34 sorted lexicographically.
35 Files in /etc/ are reserved for the local administrator, who may use
37 this logic to override the configuration files installed by vendor
38 packages. It is recommended to prefix all filenames in those
39 subdirectories with a two-digit number and a dash, to simplify the
40 ordering of the files.
41 To disable a configuration file supplied by the vendor, the recommended
43 way is to place a symlink to /dev/null in the configuration directory
44 in /etc/, with the same filename as the vendor configuration file.
45
47 All options are configured in the [PStore] section:
48 Storage=
50 Controls where to archive (i.e. copy) files from the pstore
51 filesystem. One of "none", "external", and "journal". When "none",
52 the tool exits without processing files in the pstore filesystem.
53 When "external" (the default), files are archived into
54 /var/lib/systemd/pstore/, and logged into the journal. When
55 "journal", pstore file contents are logged only in the journal.
56 Unlink=
58 Controls whether or not files are removed from pstore after
59 processing. Takes a boolean value. When true, a pstore file is
60 removed from the pstore once it has been archived (either to disk
61 or into the journal). When false, processing of pstore files occurs
62 normally, but the files remain in the pstore. The default is true
63 in order to maintain the pstore in a nearly empty state, so that
64 the pstore has storage available for the next kernel error event.
65 The defaults for all values are listed as comments in the template
67 /etc/systemd/pstore.conf file that is installed by default.
