Description of problem: While building udev rules, noticing the "BUS" key word used in some of the shipped udev rules is not documented in the udev man page. For example: $ grep BUS /lib/udev/rules.d/40-redhat.rules ACTION=="add", KERNEL=="sg[0-9]*", BUS=="scsi", ATTRS{type}=="3|6", SYMLINK+="scanner scanner-%k", MODE="0660" ACTION=="add", KERNEL=="sg[0-9]*", BUS=="scsi", ATTRS{type}=="8", SYMLINK+="changer changer-%k", MODE="0660", GROUP="disk" BUS=="usb", KERNEL=="sd*", ATTRS{bInterfaceClass}=="08", ATTRS{bInterfaceSubClass}=="04", GROUP="floppy", MODE="0660", SYMLINK+="floppy floppy-%k" $ I'm trying to develop a working rule for single path iSCSI storage so it can be documented. However the existing example in the virtualisation guide uses BUS (plus others) and isn't working "out of the box". As BUS isn't documented, it's leaving me wondering if that needs to be changed to SUBSYSTEM or something. Version-Release number of selected component (if applicable): $ rpm -qa | grep udev udev-debuginfo-147-2.6.el6.x86_64 libudev-147-2.6.el6.x86_64 libgudev1-147-2.6.el6.x86_64 udev-147-2.6.el6.x86_64 $ How reproducible: Every time. Steps to Reproduce: 1. n/a 2. 3. Actual results: Undocumented udev key word, making me wonder if the shipped rules files are wrong, or if the man page is incomplete. Expected results: All available udev key words documented. Additional info:
BUS is obsolete... use SUBSYSTEM(s)
