Module: Sysconfig_Route
Parses /etc/sysconfig/network-scripts/route-${device}
Author: Stephen P. Schaefer
About: Reference
This lens allows manipulation of *one* IPv4 variant of the
/etc/sysconfig/network-scripts/route-${device} script found in RHEL5+, CentOS5+
and Fedora.
The variant handled consists of lines like
"destination_subnet/cidr via router_ip", e.g.,
"10.132.11.0/24 via 10.10.2.1"
There are other variants; if you use them, please enhance this lens.
The natural key would be "10.132.11.0/24" with value "10.10.2.1", but since
augeas cannot deal with slashes in the key value, I reverse them, so that the
key is "10.10.2.1[1]" (and "10.10.2.1[2]"... if multiple subnets are reachable
via that router).

About: Lens Usage
Sample usage of this lens in augtool
* Set the first subnet reachable by a router reachable on the eth0 subnet
> set /files/etc/sysconfig/network-scripts/route-eth0/10.10.2.1[1] 172.16.254.0/24
* List all the subnets reachable by a router reachable on eth0 subnet
> match /files/etc/sysconfig/network-scripts/route-eth0/10.10.2.1
About: Configuration files
This lens applies to /etc/sysconfig/network-scripts/route-*
