-q Limit generated output
|
|
-p Path prefix for configuration files (e.g., during install -p mnt is used as files are mounted on /mnt).
|
|
-e Ethernet card
|
|
-a Use DHCP (-H, -i, -n, -g, -d, and -s flags are discarded)
|
|
-H Hostname
|
|
-i IP address
|
|
-n Netmask
|
|
-g Default gateway
|
|
-d Primary DNS
|
|
-s Secondary DNS
|
|
-h Shows this help file
|
