The test doesn't make sense. It just exits with error code 5 if the
binary doesn't exist, which is silly. Buildroot installs both udevd and
its init script as part of the same package. But if it ever happens for
some reason, the error message "/sbin/udevd: No such file or directory"
in the start case should be pretty clear.
Replace the UDEV_BIN variable, which was used only once, by the full
path of the binary file.

The following error occures in the udev init script because the kernel config
may optionally not include uevent_helper.
/etc/init.d/S10udev: line 47: can't create /proc/sys/kernel/hotplug: nonexistent directory
Work around this by not trying to access the destination if it's not available.

Using a variable in a printf format string may lead to undesirable
results if the variable contains format controls, so replace
printf "foo $var bar"
by
printf "foo %s bar" "$var"

Replace (echo "msg" && exit 1) by { echo "msg"; exit 1; }.
The (list) compound command runs in a subshell, so the "exit" interrupts
the subshell, not the main script. Examples:
$ sh -c "echo 1; (exit 1); echo 2"
1
2
$ sh -c "echo 1; { exit 1; }; echo 2"
1
$

Make the udev initscript trigger in a coherent way, i.e. first set
subsystems, then device and then let the whole thing settle.
Otherwise for usb_modeswitch udev rules they never kick in since the
storage aspect (device) gets claimed first and the switch ignored.
Also set the settle timeout to a smaller value than the default
120 seconds to avoid stalling too much.

This commit adjusts the S10udev script by:
* Using the --action=add option to udevadm trigger. By default, only
the "change" events are handled by 'udevadm trigger', which means
it doesn't handle all the "device add" events that occured during
the boot time, before eudev was started.
* Adds a call to 'udevadm settle' to make sure we wait for udev to
handle all the events that occured before eudev was started.
Both of these change match what the Ubuntu and Debian udev startup
scripts are doing.

eudev is a userspace device management daemon. It is a standalone
version, independent from systemd. It is a fork maintained by Gentoo.
Features:
- No extra configuration options are available: Gudev is build if
libglib2 is selected.
- No dependency on hwdata as the package uses its own hardware
database (as does systemd).
eudev 1.3 is in sync with systemd v207.
