The dracut.cmdline man page lists: ip=<client-IP>:[<peer>]:<gateway-IP>:<netmask>:<client_hostname>:<interface>: {none|off|dhcp|on|any|dhcp6|auto6|ibft}[:[<dns1>][:<dns2>]] for explicit (static) network configuration. To my old mind, "netmask" refers to something of the form 255.X.X.X. However if I use that form with EL7 or Fedora 20, it fails with a message like: Bringing up interface eth0: Error: an inet prefix is expected rather than "10.8.0.0/255.255.255.0". It works if I give it a CIDR suffix. It appears that the netmask for used to work. - Orion -- To unsubscribe from this list: send the line "unsubscribe initramfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
