Allow me to correct this:

Here is something frm an Asterisk 1.0 system. It has not radically
changedin Asterisk 1.2:

This information is generated by depmod even in 2.4 . It is extracted
from the declerations inside kernel modules code.

discover and kudzu use that information to load the relevant modules
when they are run. They scan the bus in a generally predictable order at
boot time. They don't require any special 2.6 features. But they don't
support hotplugging.

hotplug takes this to th next level: the kernel notifies userspace of
new events. This allows hotplugging.

The default configuration of zaptel from the tarball is to try to run
ztcfg (with too many v flags, mind you) after every zaptel module gets
loaded (even ztdummy, ztdynamic and zaptel, IIRC). As a result, modprobe
will fail many times due to ztcfg being run with an incomplete
configuration. 

The solution to that is to have a simple init.d script that modpobes
ztdummy if no other span is discovered and then runs ztcfg. As it has no
problems running twice, it needs no lock file.

Regarding the stop action: There is no need to rmmod those modules at
shutdown time, IMHO. Hence removing them should not be the default stop
action, should this be an init.d script.
