I tried and failed to reproduce this in an artful vm: ubuntu@mwhudson-artful:~$ cat /etc/udev/rules.d/my.rules KERNELS=="*", ACTION=="*", DEVPATH=="/devices/*", RUN+="/bin/touch /run/my-file" ubuntu@mwhudson-artful:~$ sudo rm -f /run/my-file ubuntu@mwhudson-artful:~$ sudo udevadm trigger /sys/devices/pci0000:00/0000:00:03.0/virtio2/block/vdb/vdb1 ubuntu@mwhudson-artful:~$ ls -l /run/my-file -rw-r--r-- 1 root root 0 Nov 8 23:53 /run/my-file
(and there are no interesting messages in syslog when I do this). Is the bug still affecting you? It's possible it got fixed in systemd or somewhere else in the meantime. -- 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. I don't know if you have any other better solution to this issue. root@ltc-boston123:/lib/systemd/system# diff -Naurp systemd-udevd.service.org systemd-udevd.service --- systemd-udevd.service.org 2017-09-26 04:37:47.090057318 -0500 +++ systemd-udevd.service 2017-09-26 04:37:55.381739372 -0500 @@ -25,7 +25,7 @@ KillMode=mixed WatchdogSec=3min TasksMax=infinity MountFlags=slave -MemoryDenyWriteExecute=yes +#MemoryDenyWriteExecute=yes RestrictRealtime=yes RestrictAddressFamilies=AF_UNIX AF_NETLINK AF_INET AF_INET6 SystemCallArchitectures=native -Vasant To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1719720/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
