UDEV mount event not generated

Hi all.

I'm developing an embeded thin client system based on initramfs using
debian kernel bins, and libs: www.tcosproject.org

I'm using debian unstable (udev 0.114-2 ).

My thin client remote devices manager (tcos-devices-ng.py [1]) uses udev
events, I load events using a XMLRPC server running on thin client.


1.- I have created one simple udev rule [2]:

SUBSYSTEM=="block",  RUN+="/sbin/tcos-udevd.sh"


tcos-udev.sh [2] script is called in every udev block event.


Some time ago (when I start developing this tools) I filter this events
in my python app:

self.udev_events={
  "insert":       {"ID_BUS":  "usb",         "ACTION":"add"},
  "remove":       {"ID_BUS":  "usb",         "ACTION":"remove"},
  "mount-floppy": {"DEVPATH": "/block/fd0",  "ACTION":"mount"},
  "umount-floppy":{"DEVPATH": "/block/fd0",  "ACTION":"umount"},
  "mount-cdrom":  {"DEVPATH": "/block/hd*",   "ACTION":"mount"},
  "umount-cdrom": {"DEVPATH": "/block/hd*",   "ACTION":"umount"},
  "mount-flash":  {"DEVPATH": "/block/sd*",   "ACTION":"mount"},
  "umount-flash": {"DEVPATH": "/block/sd*",   "ACTION":"umount"}
}


This is the meaning of every element:

  "udev-event-name": {"condition1":"condition1", "cond2":"cond2"}



All actions worked ok:

* add (tell thin client to mount DEVNAME)
* remove (tell thin client to umount all parts in DEVNAME)
* mount (show a message: Device XXX is ready)
* umount (show a message: You can unplug device XXX)


In 2007 June this tools works ok (don't remember udev version) [3]

I don't know when mount/umount stop working, but from some weeks ago I
can see mount/umount messages.

Why udev don't send mount/umount block events to my app?

Any ideas?
Bad rules file?


Thanks for your work
