Using scriptlet option?

[myxal]

Hi all.
I've encountered several mentions of the "ipxe.scriptlet" dhcp option (encap: 175:81) on the forums and around, but couldn't find documentation or a good example. Is it deprecated or something?

I'd like to use it to set a variable used later in the main script, so I set dnsmasq to pass this inside the option:

Code:

dhcp-option-force=<tag filters...>,encap:175,81,"set nd-option live-netdev=eth1"

Now, how do I execute it? Testing in the interactive shell, the obvious ${scriptlet} tries to use the entire string as a command name:

Code:

set nd-option live-netdev=eth1: command not found
