User may specify static route for a target address which is different
than default gateway. The static route file could be like below:
192.168.200.222 via 192.168.100.222 dev eth0
Or
ADDRESS0=192.168.200.0
NETMASK0=255.255.255.0
GATEWAY0=192.168.100.222
In this patch, port the static route hanling from ifup-routes of initscript
component.
v1->v2:
Remove the commentary line checking code and "MATCH" pattern
definition since dracut require posix syntax. Let's focus on the
functionality of static route.
