Guess I spoke too soon! After some careful study and testing, I found
that the udev.rules file has mounting/unmounting rules for usb
devices, that call /lib/udev/usbmount.sh, which conflicts with vl-hot.
It turned out vl-hot was doing the mounting, but usbmount.sh was doing
the unmounting, bith to different mountpoints, which is of course bad.
I have modified the vl-hot rules and scripts to use the /lib/udev dir,
as is now standard, instead of /etc/udev/scripts. I also made the
necessary mods to get it working with this new udev version (required
mods to 10-vl-hot.rules). I could modify usbmount.sh for our purposes,
but vl-hot is already there and more complete (if I do say so myself,
lol). The vl-hot rules are also designed to handle more than just usb
devices (which means I must check udev.rules for further interference
in the case of pccard or firewire drives). Anyway, I suggest we stick
to vl-hot for now, meaning some stuff has to be commented out in
udev.rules. So far this is limited to the usb devices in lines 24 and
26, like this:

# USB storage devices
#KERNEL=3D"sd?[0-9]*", ACTION=3D=3D"add", BUS=3D=3D"usb", NAME=3D"%k",
SYMLINK=3D"usbmedia%e", GROUP=3D"cdrom", MODE=3D"0660",
RUN+=3D"/lib/udev/usbmount.sh add /dev/%k"
KERNEL=3D"ub?[0-9]*", ACTION=3D=3D"add", BUS=3D=3D"usb", NAME=3D"%k",
SYMLINK=3D"usbmedia%e", GROUP=3D"cdrom", MODE=3D"0660",
RUN+=3D"/lib/udev/usbmount.sh add /dev/%k"
#KERNEL=3D"sd?[0-9]*", ACTION=3D=3D"remove", RUN+=3D"/lib/udev/usbmount.sh
remove /dev/%k"
KERNEL=3D"ub?[0-9]*", ACTION=3D=3D"remove", RUN+=3D"/lib/udev/usbmount.sh
remove /dev/%k"

I'll leave the ub devices to usbmount.sh, lol.

I'm calling this a new branch of vl-hot, 0.3.0, and it's committed to
the SF cvs already. If you want it and don't want to mess with the cvs
yet, just let me know.
