COREDUMP.CONF(5) | coredump.conf | COREDUMP.CONF(5) |
NAME¶
coredump.conf, coredump.conf.d - Coredump storage configuration files
SYNOPSIS¶
/etc/systemd/coredump.conf
/etc/systemd/coredump.conf.d/*.conf
/run/systemd/coredump.conf.d/*.conf
/usr/lib/systemd/coredump.conf.d/*.conf
DESCRIPTION¶
These files configure the behaviour of systemd-coredump(8), a handler for core dumps invoked by the kernel.
CONFIGURATION DIRECTORIES AND PRECEDENCE¶
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/. Files in /etc/ are reserved for the local administrator, who may use this logic to override the configuration files installed by vendor packages. 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 which of the subdirectories they reside in. If multiple files specify the same option, the entry in the file with the lexicographically latest name takes precedence. 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.
OPTIONS¶
All options are configured in the "[Coredump]" section:
Storage=
When cores are stored in the journal, they might be compressed following journal compression settings, see journald.conf(5). When cores are stored externally, they will be compressed by default, see below.
Compress=
ProcessSizeMax=
ExternalSizeMax=, JournalSizeMax=
MaxUse=, KeepFree=
