udev rules -- file names -- just wondering??
Hi; I am looking at /etc/udev/rules.d, particularly 90-alsa.rules and noticed that all the udev rules files are preceded by a number in their name. Is that number significant? Or is it used just to avoid duplicate names? I was looking to see if I could chase down why undev produces a wierd beep when it initiates on boot. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 22.3.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

The number indicates the order in which the rules are applied, similar to the number preceding startup/shutdown scripts in /etc/rc?.d poc -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

Perhaps it is the same as this bug? https://bugzilla.redhat.com/show_bug.cgi?id=495166 It probably is. I will add my comments to the bug. However, I am still having several difficulties with ALSA -- same difficulties as many people have already posted here. Some of the problems are being blamed on PulseAudio which may not, in fact, be the culprit. I have completely removed PulseAudio and my problems remain. If I can get ALSA working in a stable manner I will re-introduce PulseAudio and see what happens. I think -- for whatever that is worth -- there is a a single bug in one of the fundamental processes; ALSA, udev, hal, d-bus, the kernel or DeviceKit that was introduced by an upgrade. By the way, I am still curious about the significance of the two digit prefix on udev/rules/ files. Man udev and udevd are silent on this. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 22.3.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

This can be important if a rule stops further rule processing for a specific device. The rules do not have to have a number, but it makes fowling the order of rules easier. The processing order it the same as the sorted ls order.
