Can you provide a documentation patch describing the sysfs layout for

The only way we are going to avoid breaking this repeatedly is to get
serious around documentating the variants we need to support then then
testing them. The example output from iscsidam tool then can be used to
build a fake iscsiadm tool invoked by the test suites exercising all the
new code.
I didn't get all of the information you requested (yet). But I did connect a
number of different kernels up to an iSCSI target and look at the listing in
/sys/bus/scsi/devices/target:channel:id:lun
Kernel iscsi-initiator-utils sysfs
2.6.9 4.0.3.0-6 block/sda1, block/sda2 (note no block/sda!)
2.6.18 6.2.0.868-0.7.el5 block:sda
2.6.21 6.2.0.865-0.2.fc8 block:sda
2.6.25 6.2.0.868-0.7.fc9.i386 block/sda
Now, we probably don't care about 2.6.9. So that leaves the other few kernels,
which all seem to follow either the block:sda or block/sda pattern. So, at
least for now, Stefan can test my patch to see if it helps him. I'll try to
collect further information, including the output from iscsiadm.
