I’ve found out a better and more elegant way than this usual: touch /etc/rc.d/rc.local echo "touch /var/lock/subsys/local" > /etc/rc.d/rc.local echo "route add default gw 10.10.0.1 eth0" > /etc/rc.d/rc.local echo "route add -net 10.1.0.0 netmask 255.255.0.0 gw 10.2.0.1 eth0" > /etc/rc.d/rc.local Inside Fedora GNU/Linux, static routes can be added in specific files for each one of its interfaces. These files are located at /etc/sysconfig/network-scripts/. The filename must match the route-ifname format.

A situation that makes me angry for years is when you have attributes that work as flags inside tables. Think twice (or maybe three times) before create them because usually, they are unnecessary. And why? We create them to mark a state of a record, which can be done, many times, querying another attributes, generating duplicity situations (so much problematic, per si).
