[Dnsmasq-discuss] ProxyDHCP mode is broken for serving ipxe.efi to UEFI pxe clents

[Dreamcat4]

In the meantime,

Have setup an auto-builds. To make linux binary tarball of last released
version. In debian / ubunt filesystem layout.

Added with the necessary (but missing) uefi patch ^^ from Micahael


Its built here:

https://github.com/dreamcat4/docker-images/blob/master/linux-bin/Dockerfile#L26-63



Binary is available here:

https://dl.bintray.com/dreamcat4/linux/dnsmasq/


Haven't tested it for myself yet. (but will try soon). Hope it works.


Kind Regards
Dreamcat4
