Subject: Remove temporary files at startup.
X-Git-Url: http://git.meshlink.io/?p=meshlink;a=commitdiff_plain;h=4bfa6c6c9749fb3d8b73734ec7aa1ca51f813b5f

Remove temporary files at startup.

When something happens while a host config files is written, a temporary
file might be left over. Clean these up when we find them when starting
MeshLink.
