Subject: Treat netname="." in a special way.
X-Git-Tag: release-1.0.14~38
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=aca70cd3c3fe787e62c618849e43f67b3870ac20

Treat netname="." in a special way.

Treat netname "." in a special way as if there was no netname
specified.  Before, f.e. tincd -n. -k didn't work as it tried
to open /var/run/tinc-.pid.  Now -n. works as if there was no
-n option is specified.
