Problem with udev rules under etch

[Andy Hawkins <andy@gently.org.uk>]

Hi all,

Yesterday I upgraded my system to etch, and now my udev rules aren't working
any more. I've had a read of the man pages and have changed one of them (for
my parallel ZIP drive) to read:

SUBSYSTEMS=="scsi", ATTR{model}=="ZIP 100", KERNEL=="sd?4",  NAME=="%k",
        SYMLINK+="zip"

(I've wrapped this line for clarity, it appears all on one line in the file)

udevinfo -a -p $(udevinfo -q path -n /dev/sda)

reports:


Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

  looking at device '/block/sda':
    KERNEL=="sda"
    SUBSYSTEM=="block"
    DRIVER==""
    ATTR{stat}=="      10        7      136     1256        0        
0        0        0        0     1256     1256"
    ATTR{size}=="196608"
    ATTR{removable}=="1"
    ATTR{range}=="16"
    ATTR{dev}=="8:0"

  looking at parent device '/devices/platform/host9/target9:0:6/9:0:6:0':
    KERNELS=="9:0:6:0"
    SUBSYSTEMS=="scsi"
    DRIVERS=="sd"
    ATTRS{ioerr_cnt}=="0x5"
    ATTRS{iodone_cnt}=="0x26"
    ATTRS{iorequest_cnt}=="0x26"
    ATTRS{iocounterbits}=="32"
    ATTRS{timeout}=="30"
    ATTRS{state}=="running"
    ATTRS{rev}=="D.13"
    ATTRS{model}=="ZIP 100         "
    ATTRS{vendor}=="IOMEGA  "
    ATTRS{scsi_level}=="3"
    ATTRS{type}=="0"
    ATTRS{queue_type}=="none"
    ATTRS{queue_depth}=="1"
    ATTRS{device_blocked}=="0"

  looking at parent device '/devices/platform/host9/target9:0:6':
    KERNELS=="target9:0:6"
    SUBSYSTEMS==""
    DRIVERS==""

  looking at parent device '/devices/platform/host9':
    KERNELS=="host9"
    SUBSYSTEMS==""
    DRIVERS==""

  looking at parent device '/devices/platform':
    KERNELS=="platform"
    SUBSYSTEMS==""
    DRIVERS==""

So as far as I can tell, matching against the model attribute in the scsi
section should work. However, I'm not getting the symlink created.

if rules match against subsystem specfic kernel event variables.

So, it's read in my 'local.rules' file (which is where the rule I quoted
above was) but hasn't done anything as it doesn't appear to have found a
match.

Can anyone offer any assistance? As none of my rules are working, I suspect
that if I can work out what I've done wrong for this one I should be able to
apply it to the others.

Thanks in advance for any assistance

Andy
