Is there a problem calling "nvram set" inside a custom script?

[Nazgulled]

Following the solution to a particular problem on this thread, I was wondering if there is any kind of problem or danger in calling "nvram set" command inside a custom script?

In this particular case, I'm calling nvram set wan1_dns="(...)" inside the dnsmasq.postconf script.

Is this OK to do?

I don`t see a problem doing that...
