Subject: client: translate dot into the short hostname
X-Git-Tag: 1.0.18~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b8955080cb5ff8e24479cc6638d420ca9c0d9817;p=thirdparty%2Flldpd.git

client: translate dot into the short hostname

as documented in lldpcli(8):

    configure system hostname name

        Override system hostname with the provided value. By default, the
        system name is the FQDN found from the resolved value of uname
        -n.  As a special value, use "." (dot) to use the short hostname
        instead of a FQDN.
