Put it differently: If you want to use 2.4.0-test (and prerelease) kernels, use the 2.3.* modutils. As it stands, we saw a bug report this morning about how 2.4 modutils broke hotplugging with 2.2 kernels, since it created unusable (empty) "usbmap" files ... you're not as backwards-compatible as you may think you are! I think it's reasonable not to want to support 2.4-test kernels; anyone trying to use one of them has no reason to expect support. > Isn't it true that the /sbin/hotplug support code simply doesn't > exist in older kernels? No; it's in the 2.2 backport (thanks to Greg) and current hotplug scripts should work on 2.2 kernels too. If (!) people don't try to use the 2.4 modutils ... the empty/unusable "usbmap" breaks things. One more point on the "no *_device_id => no mapfile" side. That can be kluged around in usermode, but it's an incompatibility. - Dave _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
