Heuristic to break DHCP infinite loop

[alkisg]

I just noticed the almost undocumented scriptlet option. This is even better than the heuristic that I suggested.

So now I just want to suggest that scriptlet gets documented in https://ipxe.org/cfg/scriptlet and in https://ipxe.org/howto/chainloading.

For dnsmasq, an example syntax is:

Code:

dhcp-option-force=encap:175,81,"ifopen && chain ltsp/ltsp.ipxe || shell"

P.S. keep in mind that scriptlet won't work if iPXE is booted locally, from ipxe.iso etc; it will only work if ipxe.pxe, undionly.kpxe etc are loaded over the network, so that scriptlet is there even before the "dhcp" command is run.
