NFS vmount problem

AIX's NFS client sends requests on high port numbers by default, and
Linux rejects this as the security exposure it is. On AIX i'm use:

nfso -o nfs_use_reserved_ports=1

But how i can setup it in autorun? /etc/rc.local right way ?

to set this in /etc/tunables/nextboot

when you make this chnage
nfso -o nfs_use_reserved_ports=1 it only updates it for now
but by using this

nfso -o -p nfs_use_reserved_ports=1

Makes changes apply to both current and reboot values, when used in combination with -o, -d or -D, that is, it turns on the updating of the /etc/tunables/nextboot file in addition to the updating of the current
value.
