Greetings,
I'm seeing some unexpected behavior for my systemd --user process.
Background:
I've setup udev rules to fire off systemd --user units to download photos
when my camera (PTP device) or my phone (MTP device) get plugged in. They
are both USB devices:
==> /etc/udev/rules.d/90-canon-60d.rules <==
# Download photos from Canon 60D
ACTION=="add" \
ENV{GPHOTO2_DRIVER}=="PTP" \
ENV{ID_VENDOR_ID}=="04a9" \
ENV{ID_MODEL_ID}=="3215" \
TAG+="systemd" \
PROGRAM="/bin/systemd-escape --template=download-photos at .service
Canon_60D_$env{ID_VENDOR_ID}_$env{ID_MODEL_ID}" \
ENV{SYSTEMD_USER_WANTS}+="%c"
==> /etc/udev/rules.d/90-galaxy-note-3.rules <==
# Download photos from Galaxy Note 3
ACTION=="add" \
ENV{ID_MTP_DEVICE}=="1" \
ENV{ID_VENDOR_ID}=="04e8" \
ENV{ID_MODEL_ID}=="6860" \
ENV{ID_SERIAL_SHORT}=="17b765cc" \
TAG+="systemd" \
PROGRAM="/bin/systemd-escape --template=download-photos at .service
$env{ID_SERIAL}" \
ENV{SYSTEMD_USER_WANTS}+="%c"
==> ~/.config/systemd/user/download-photos at .service <==
[Service]
Type=oneshot
ExecStart=/usr/bin/mate-terminal --maximize --command '/usr/bin/imagdo
--config-file %h/.imagdo/conf/%I.yaml'
SuccessExitStatus=0 255
However, after plugging in my phone, I need to run:
systemctl --user daemon-reload
in order to get udev/systemd to recognize my camera being plugged in and
fire off the "download" script.
Here are the logs from the journal of the download working for my phone:

Any ideas what to look for or how to fix the need to run the daemon-reload
between plugging in the two USB devices?
Thanks!
