Initialize the defaults in udev_config.c instead of namedev.c.
Replace macro by expanded code. Switch to mode_t instead
of string value. Add and clarify some comments.
Remove udev.bus, cause it's currently unused and newer kernels will pass
it in the hotplug environment as PHYSDEVBUS.
Remove udev.action, cause it's unused.
Rename udev_set_values() to udev_init_device().
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.
The /etc/dev.d/input/input.dev was called twice for /dev/input/mouse.
Skip the execution if we get a directory named after the subsystem.
Move UDEV_NO_DEVD where it belongs.
This cuts the size of the binaries, as only objects that
are actually used are linked into the binary:
45592 -> 43608 udev
4380 -> 4380 udevsend
10380 -> 4652 udevd
34732 -> 33100 udevinfo
45432 -> 37208 udevtest
I just noticed that the DEVNAME enviroment variable isn't being set anymore
in udev 0.046 on device removal, while it was being set in 0.042. We're using
the property tto do umount -l <devices> when a block device is removed. Afaik
there is no other way to associate a device with it's DEVNAME on removal ?
Also are there cases where doing umount -l on the removed devices is wrong?
I guess the device is gone, so there is no sense in keeping it mounted (it's
not like the filesystem is gonna come back in a sane state again)..
Attached (trivial) patch brings back the DEVNAME variable on device removal.

The slow logging facilites on some systems are a reason for
the reported slowness of udevstart. On one of my boxes udevstart
is down from 9 second to 0.3 seconds.
Some broken ide drivers are generating high event traffic, with
add/remove events. With this attribute, it can be specified,
that the node is always available. It may be used in conjunction
with the new DRIVER= match to catch specific kernel device drivers.
