Title:
udev rule read but "RUN" command is not executed
Status in systemd package in Ubuntu:
Invalid
Bug description:
The following was introduced as
"/etc/udev/rules.d/99-harvest_camera.rules":
ACTION=="add", KERNEL=="sd*[!0-9]", ENV{ID_FS_UUID_ENC}=="C355-A42D",
RUN+="/usr/bin/sudo -u bill /home/bill/scripts/harvest_camera.sh"
When the device is attached, it gets mounted but the harvest_camera.sh
script does not execute. The udev_log=debug parameter is set in
/etc/udev/udev.conf. Verbosity was also maximized by running "udevadm
control --log-priority=debug". After running "udevadm monitor
--environment --udev", the drive was attached. The output shows a
device being created (/dev/sda1) and the UUID in the rule matches.
But the script simply never executes. The /var/log/syslog file shows:
"
Reading rules file: /etc/udev/rules.d/99-harvest_camera.rules
Successfully forked off 'n/a' as PID 2201.
1-2.3: Worker [2201] is forced for rocessing SEQNUM=7973.
"
So the logs make it look as though the script was executed. The
script is simply a stub that does a "touch /tmp/IhaveExecuted" and a
call to zenity to give a popup announcement. But none of that happens
(no popup and no new file in /tmp/). With maximum verbosity, there is
no way to further diagnose this. Deeper detail is needed that shows
which matching criteria in the rules is being tried and what the
result is.
