Bug#856924: systemd: on WorkingDirectory not existing, some weird log about CHROOT is generated

[Salvo Tomaselli]

Package: systemd
Version: 232-19
Severity: normal

Dear Maintainer,
I have created a unit file like this

[Unit]
Description=lala

[Service]
WorkingDirectory=/does/not/exist
ExecStart=/bin/sh -c "echo ciao"

[Install]
WantedBy=multi-user.target

And when I try to start it I obtain
lala.service: Failed at step CHROOT spawning /bin/sh: No such file or directory

which makes it seem like /bin/sh is not found, when actually the issue is that
WorkingDirectory doesn't exist.

Perhaps a log message related to the actual error would be of more use.

Best
