This field can be used to append arbitrary text to the configuration file. It
is especially useful for elaborate configurations that cannot be expressed
otherwise. This configuration, for example, would generally disable root
logins, but permit them from one specific IP address:
@example
(openssh-configuration
(extra-content "\
Match Address 192.168.0.1
PermitRootLogin yes"))
@end example
@end table @end table
@end deftp @end deftp
