Correct. We just stamp that file and used to trigger vpdupdate automatically.. So if timestamp of this file is newer than last updated vpd information (vpd.db file), then next time when someone run lsvpd/lscfg tools vpdupdate will be triggered automatically. > > However, I don't understand how the absence of this file is causing a > problem.

Impact is, if we don't have this file, then if something changes in VPD information, someone has to run vpdupdate manually. If we have this file, then it will trigger vpd database update automatically.. Earlier we had several bugs for this purpose.. (like after hotplug I don't see information in VPD database) and people don't wanted to run vpdupdate command manually. Hence we used this method. > > And putting a file such as this into a shared library package means that any > new version of the library with a new ABI will have to declare a Replaces: > against the older versions of the library, which is not ideal - however this > problem already exists because of the udev rules file. > > In any case, please explain why you believe the absence of this file is a > bug. As explained above without this file, user has to run vpdupdate command manually after changing device configuration.. Otherwise they will endup getting stale data.. And one might think that its VPD bug! (In the past we had several bug reported related to this issue). -Vasant -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492895 Title: Ubuntu 14.04.03 Missing file - run.vpdupdate in libvpd package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvpd/+bug/1492895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
