SYSTEMD_SERVICE_${PN} should just be set to the service name, not the full path. So…
SYSTEMD_SERVICE_${PN} = "testapp-extra@.service"

Also, consider using ${systemd_system_unitdir} instead of ${systemd_unitdir}/system

Cheers!

Subject: [yocto] Install systemd unit file into image from source?

I've got an application that I'd like to install into my custom image and that application has a couple of associated systemd unit files that should be installed as well. The application itself is a very simple cmake project. The relevant bits of the recipe file look something like this:
```
<standard variables go here>

SRC_URI = "<git address goes here>"

S = "${WORKDIR}/git"

inherit systemd
SYSTEMD_AUTO_ENABLE = "enable"
# the service files are stored in the git repository in the misc folder
SYSTEMD_SERVICE_${PN} = "${S}/misc/testapp@.service ${S}/misc/testapp-extra@.service<mailto:$%7bS%7d/misc/testapp@.service%20$%7bS%7d/misc/testapp-extra@.service>"

do_install_append() {
    install -d ${D}${systemd_unitdir}/system
    install -m 0644 ${S}/misc/testapp@.service<mailto:$%7bS%7d/misc/testapp@.service> ${D}${systemd_unitdir}/system/
    install -m 0644 ${S}/misc/testapp-extra@.service<mailto:$%7bS%7d/misc/testapp-extra@.service> ${D}${systemd_unitdir}/system/
}

inherit cmake
```

When i try to do do `bitbake testapp` to try out the recipe, I get an error telling me that: SYSTEMD_SERVICE_testapp value /projects/poky/build/tmp/work/core2-64-poky-linux/testapp/0.1-r0/git/misc/testapp@.service does not exist.

I'm using yocto 3.2.1 if that matters.
