kdb-mount - Mount a file to the key database


kdb mount [<path> <mountpoint>] [<plugin> [<config>] [..]]

· Where path is the path to the file the user wants to mount. See kdb info resolver for
details what an absolute and relative path means.

· mountpoint is where in the key database the new backend should be mounted. (For a
cascading mount pount, mountpoint should start with /)

· plugin should be an Elektra plugin. A list of such plugins with configuration can be

· Plugins may be followed by a , separated list of keys and their corresponding values
which will be written below the backend configuration.


This command allows a user to mount a new backend.

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

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.


-H, --help
Show the man page.

-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

-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.

-1, --first
Suppress the first column.

-2, --second
Suppress the second column.

-3, --third
Suppress the third column.

-c, --plugins-config
Add a plugin configuration for all plugins.


The resolver that will be added automatically, if -R is not given.

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
kdb mount /etc/file system/file plugin1 plugin1config=config1 plugin2

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
