Incorrect attempt to use root-path

An example root-path that you have confirmed to have this issue, as well as version number based on git commit that is shown as 1.0.0+ (gitid).
Both for old version without issue and the new one with issue.

also please try git master to see if it is resolved there, there is also precompiled files available at http://boot.ipxe.org

Example root-path (served by dnsmasq, so this is dnsmasq syntax):

Code:

dhcp-option=option:root-path,192.168.200.201:/lincor/terminals

*Working* version is as packaged for Ubuntu 14.04: this is git commit #c3d1e78;
git HEAD on master that I originally tried is commit #ed0d7c4;
My modified (and working) version is based on #ed0d7c4 with the patch shown in my original post;
Very latest master, just pulled a few minutes ago, is commit #309c588, and this still displays the issue.

I tried attaching some screen-grabs but for some reason the upload failed. The error actually reported (by the latest version) is:

Code:

Could not open SAN device: Operation not supported (http://ipxe.org/3c092003)
No more network devices

The working versions (Ubuntu, and latest with my own patch) report instead:

Code:

Ignoring unsupported root path

and then continue to boot properly (and from looking at the code, that warning message is not unexpected).

I haven't tried any pre-built binaries other than that in the Ubuntu 14:04 distro, since I have it working with a simple patch to the latest.
