I'm not sure if tee is included in a standard installation, though.

Why the changes in the name of the headings?

In general I agree with the changes but there is a better way to do this.

1. systemctl --user edit msyncd
2. Paste this into the opened editor:

[Service]
Environment=QTCONTACTS_SQLITE_TRACE=1 
Environment=MSYNCD_LOGGING_LEVEL=8 
Environment=QTCONTACTS_SQLITE_TWCSA_TRACE=1

3. systemctl --user restart msyncd
4. journalctl --user --boot --unit msyncd.service
5. If the --user filter doesn't work try /usr/bin/msyncd instead of --user ---unit msyncd.service

To revert remove rm ~/.config/systemd/user/msyncd.service.d/override.conf

Doing so will ensure that the logfile will only contain output from the msyncd service.

In general calling journalctl to log something from the user session without filters is bad as it contains to much irrelevant information.

LGMT.

The proposed changes make sense and look good to me.
