@ -21636,6 +21636,28 @@ This is the list of available plugins for virtual private networks
(VPNs). An example of this is the @code{network-manager-openvpn}
package, which allows NetworkManager to manage VPNs @i{via} OpenVPN.
@item @code{extra-configuration-files} (default: @code{'()})
A list of two-element lists; the first element of each list is a file
name (as a string), and the second is a file-like object. Used to
specify configuration files which will be added to the
@file{/etc/NetworkManager/conf.d}. NetworkManager will read additional
configuration from this directory. For details on configuration file
precedence and the configuration file format, see @samp{man 5
NetworkManager.conf}.
For example, to add two files named @file{001-basic.conf} and
@file{002-unmanaged.conf}:
@lisp
(service network-manager-service-type
(network-manager-configuration
(extra-configuration-files
`(("existing-file" ,(local-file "001-basic.conf"))
("constructed-file" ,(plain-file "002-unmanaged.conf"
"[keyfile]
unmanaged-devices=interface-name:wlo1_ap\n"))))))
@end lisp
@end table
@end deftp
