Hi, first of all, take a look at man:tmpfiles.d to replace the whole mkdir/chmod ExecStartPre= stuff. Second, don't use »su« in .service. It breaks stuff by creating a new cgroup hierarchy because it's run through pam. Use User= instead. With both this changes your shell scripts shouldn't be necessary at all and than everything should land in the journal. Please don't re-invent the stuff systemd is already providing.
