Currently udevd delays only events for the same DEVPATH.
Example of an "add" event sequence:
/block/sda
/block/sda/sda1
With this change, we make sure, that the udev process handling
/block/sda has finished its work (waited for all attributes,
created the node) before we fork the udev event for /block/sda/sda1.
This way the event for sda1 can be sure, that the node for the
main device is already created (may be useful for disk labels).
It will not affect any parallel device handling, only the sequence
of the devices directory chain is serialized. The 10.000 disks
plugged in will still run as parallel events. :)
The main motivation to do this is the program execution of the
dev.d/ and hotplug.d/ directory. If we don't wait for the parent
event to exit, we can't be sure that the executed scripts are
run in the right order.

Add UDEV_LOG to the man udev man page. Remove mention of specific
variables from the udevd/udevsend man page as we changed to pass
the whole environment.
Correct printed Usage: of udevtest and udevinfo.
Init the config in udevtest earlier to accept input with and without
the sysfs mount point.

Thanks Eric, udevsend.8 is only a symlink to udevd.8, so I attached a
stripped down patch to this mail.

I have a very slow Bluetooth adapter hotplug event call, so we need
to increase the event timeout to something larger than 6 seconds.

Based on a an original patch from Olaf Hering <olh@suse.de>
|

Thanks to Christian Gierke, he sent me a beauty patch for our man pages.
Some typos are fixed and a few word are clarified.
|

Hey it's not longer the "goal" to provide a dynamic dev directory,
we have just arrived. So I change it to more self-confident words :)
I've also added the completly missing environment variables to the
man pages.
To stop the misuse of the PROGRAM= call paramenters, we better mention
its limitations.

Nice, here is the corresponding man update which also removes the
mention of the limitation of getgrname() and friends with klibc.
|
|
Add the new %s{filename} to the udev man page.
And add the automatic start of udevd to the udevd man page.
|
|
Here is the missing man page for udevd/udevsend.
