We carried the the old callout part selector syntax for two releases
now after it was replaced by the new %c{1} syntax. So here we remove
the old syntax and use the code to possibly specify the maximum count
of chars to insert into the string. It will work with all of our format
chars.
I don't know if somebody will use it, but the code is already there :)
's%3s{vendor}' returns "IBM" now, instead of "IBM-ESXS".
Also added is a test for it and a few words in the man page.

# udev-test
|
|
#
|
|
# Provides automated testing of the udev binary.
|
|
# The whole test is self contained in this file, except the matching sysfs tree.
|
|
# Simply extend the @tests array, to add a new test variant.
|
|
#
|
|
# Every test is driven by its own temporary config file.
|
|
# This program prepares the environment, creates the config and calls udev.
|
|
#
|
|
# udev reads the config, looks at the provided sysfs and
|
|
# first creates and then removes the device node.
|
|
# After creation and removal the result is checked against the
|
|
# expected value and the result is printed.
|
|
#
|
|
# happy testing,
