Subject: Make systemd service file handling identical to tinc 1.1.
X-Git-Tag: release-1.0.34~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a563e6dd8c88865351c05ebc72de86dac7a839d5;p=oweals%2Ftinc.git

Make systemd service file handling identical to tinc 1.1.

This removes hardcoded paths from systemd unit files, and sets the default
systemd unit path to ${libdir}/systemd/system. The configure option is now
renamed to --with-systemd[=PATH]. These changes now also ensure that
make distcheck runs without any errors.

Closes #160 on GitHub.
