Don't call the 'if{up,down}-routes' scripts because in next Fedora
versions network scripts will be deprecated and will not be present in
the default installation.
Instead, just copy and adapt the code from those scripts.

# This script applies policy-based routing rules defined for the
|
|
# connection in the /etc/sysconfig/network-scripts/ directory.
|
|
#
|
|
# This should be installed in both dispatcher.d/ and
|
|
# dispatcher.d/pre-up.d/
|
|
#
|
|
# pre-up scripts delay activation of the device. To reduce the delay,
|
|
# it is advised to install the script as symlink to no-wait.d directory.
|

|
|
# This file is derived from scripts 'if{up,down}-routes' from
|
|
# Fedora/RHEL initscripts.
