Re: udev rules and scripts (erc timeout fix)

Hello,

managed to test and bugfix the udev rules.

Simply dropping all files into /etc/udev/rules.d/ is enough, and
an "udevadm test /block/<drive_dev>/<partition_dev>" (dryrun) for a
raid member seems to run ok and tells me it would execute the
appropriate script.

However, for me, un- and re-plugging a device still does not seem to
execute the script. The _possibly-redundant-disk.sh currently logs
into /tmp/timeout-tst, but udev events don't appear there.

If you have the possiblity to test this in your /etc/udev/rules.d/
setup, it would be much appreciated.

Cheers,
Chris
