(* 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).
