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