Been investigating perminetly changing the MTU size in the setup scripts.

This is what I have tried but failed to get it to make changes

added wherever #added appears (note did not use "#added" in the actual scripts)

The vif-route script in /etc/xen/scripts contains
__________________________________________________
dir=$(dirname "$0")
. "$dir/vif-common.sh"

main_ip=$(dom0_ip)

case "$command" in
    online)
        ifconfig ${vif} ${main_ip} netmask 255.255.255.255 up
#added          if [[ "${vif}" == "peth0" ]] ; then
   #added         else
    #added         ifconfig ${vif} mtu 1492
     #added      fi
        echo 1 >/proc/sys/net/ipv4/conf/${vif}/proxy_arp
        ipcmd='a'
        ;;
    offline)
        ifdown ${vif}
        ipcmd='d'
        ;;
___________________________________________________

I tried adding the lines above but it had no effect on the interface. I guess i dont understand when this scipt is run or some other fundamental components....I'm no programmer. Can anyone tell me why it only changes the eth0 interface on dom0?????
