I agree with Erich, for 3.8.0 it should be better to continue to use the
well-tested discover+udev approach. Moreover remember that 2.4 kernels
will not work without discover, since they don't support udev and sysfs.
This means that if we want to support some old distributions, still used
in production, like RHEL3, SLES8, etc we can't totally replace discover
yet... but we could decide at runtime if it's correct to use an approach
or another depending on the running kernel. IMHO this solution needs
more than a simple script, so it could be dangerous to have this in 3.8.0.

If you agree the plan could be the following:
- now (within today) I open the 3.8.0 branch on svn
- in 3.8.0 we'll include only bugfixes and we'll try to update the
documentation (in particular the pdf manual... hey... it shouldn't be
too bad to have an updated offline documentation other than the wiki)
- in the trunk we try to integrate Erich's script (that will be used
only with 2.6 kernels)
- and maybe we could open also a "-udevtrigger" branch to do some
scouting with udevtrigger

What do you think?
