lightmediascanner doesn't start on first boot on Raspberry Pi 3 and 4

Fixed

Description

Hi,

During other routine testing, I have noticed that lightmediascanner fails to start on first boot:

● lightmediascanner.service - Lightmediascanner (LMS) Loaded: loaded (/lib/systemd/system/lightmediascanner.service; enabled; vendor preset: enabled) Active: failed (Result: timeout) since Wed 2019-10-09 11:17:22 UTC; 15s ago Process: 358 ExecStart=/usr/bin/lightmediascannerd --startup-scan --db-path=/var/volatile/tmp/lightmediascannerd> Main PID: 358 (code=exited, status=0/SUCCESS) Oct 01 05:49:32 raspberrypi4 systemd[1]: Starting Lightmediascanner (LMS)... Oct 09 11:17:22 raspberrypi4 systemd[1]: lightmediascanner.service: Start operation timed out. Terminating. Oct 09 11:17:22 raspberrypi4 systemd[1]: lightmediascanner.service: Failed with result 'timeout'. Oct 09 11:17:22 raspberrypi4 systemd[1]: Failed to start Lightmediascanner (LMS).

After rebooting the systemd services starts successfully:

● lightmediascanner.service - Lightmediascanner (LMS) Loaded: loaded (/lib/systemd/system/lightmediascanner.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2019-10-01 05:49:26 UTC; 1 weeks 1 days ago Main PID: 275 (lightmediascann) Tasks: 3 (limit: 4915) Memory: 8.3M CGroup: /system.slice/lightmediascanner.service └─275 /usr/bin/lightmediascannerd --startup-scan --db-path=/var/volatile/tmp/lightmediascannerd.db --di> Oct 01 05:49:25 raspberrypi4 systemd[1]: Starting Lightmediascanner (LMS)...

I've chatted with regarding this issue. He suggested it might be caused by a race condition between /var/volatile/tmp being created. I will investigate further.

Best regards,
Leon
