How do we proceed with this bug? any update? -Vasant -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1719720 Title: [LTCTest][libvpd] Process '/bin/touch /run/run.vpdupdate' failed with exit code 127 Status in The Ubuntu-power-systems project: Triaged Status in coreutils package in Ubuntu: Triaged Bug description: ---Problem Description--- Currently syslog is getting flooded with below log messages ..

Ok. .this is the continuation of LTC #144627 / Launchpad #1682774. As suggested in that bug, we did change udev script to create temporary file under /run and that patch is available in ubuntu 17.10. Looks like this is udev script issue. If I modify systemd-udevd like below it works fine. I've limited udev knowledge.
