md_doc_help_kdb-mount(3) Mount a file to the key database


This command allows a user to mount a new backend.

The idea of mounting is explained in elektra-mounting(7).

Mounting in Elektra allows the user to mount a file into the current key database like a user may mount a parition into the current filesystem by creating a backend. This functionality is key to Elektra as it allows users to build a global key database comprised of many different conifguration files. A backend acts as a worker to allow Elektra to interpret configuration files as keys in the central key database such that any edits to the keys are reflected in the file and vice versa. Additionally, the user can use this command to list the currently mounted backends by running the command with no arguments.


This command writes into the /etc directory and as such it requires root permissions. Use kdb file system/elektra/mountpoints to find out where exactly it will write to.

  • -V, --version: Print version info.
  • -d, --debug: Give debug information or ask debug questions (in interactive mode).
  • -i, --interactive: Instead of passing all mounting information by parameters ask the user interactively.
  • -R, --resolver <name>: Specify the resolver plugin to use if no resolver is given, the default resolver is used. See also /sw/kdb/current/resolver below.
  • -0, --null: Use binary 0 termination.

  • -2, --second: Suppress the second column.
  • -3, --third: Suppress the third column.
  • -c, --plugins-config: Add a plugin configuration for all plugins.


  • /sw/kdb/current/resolver: The resolver that will be added automatically, if -R is not given.
  • /sw/kdb/current/plugins: It contains a space-separated list of plugins which are added automatically (by default sync).


To list the currently mounted backends: kdb mount

To mount a system configuration file using the ini format: kdb mount /etc/configuration.ini system/example ini

Print a null-terminated output of paths and backend names: kdb mount -02 | xargs -0n 2 echo

To mount the /etc/file system file with two plugins with a respective configuration option each: kdb mount /etc/file system/file plugin1 plugin1config=config1 plugin2 plugin2config=config2

To mount the /etc/file system file with two plugins and setting both to be verbose: kdb mount -c verbose=1 /etc/file system/file plugin1 plugin2

To recode and rename a configuration file using Elektra: kdb mount s.ini recode.txt ni rename cut=path iconv recode=utf8..latin1
