udev + modprobe

[Oliver Martin <spam@dodgit.com>]

(seems my last message didn't get through...)

Hello,

I am trying to make udev load required modules as devices are plugged
in, so I wrote this rule:

ATTR{modalias}="?*", ACTION="add", RUN+="/sbin/modprobe $env{MODALIAS}"

However, when I plug in a USB drive, nothing happens. But now comes the
weird bit: If I save MODALIAS to a file (with the same rule, only a
modified command) and later run modprobe manually, it loads usb-storage
just fine!

This happens with udev-106 and Busybox 1.4.2, as installed by ptxdist
(an embedded userland builder). udev itself is working fine and creates
the correct device nodes if the modules are already loaded. Any ideas
what my problem could be?


Thanks,
Oliver
