[syslinux] How to support iSCSI multipath...

[Miller, Shao]

Hello Alex,

In regards to your question regarding passing multiple paths for
fault-tolerance (I assume) in the iBFT:

A slight correction: gpxelinux.0 = undionly.kkpxe (gPXE) + pxelinux.0
(PXELINUX)

I'm not sure why you'd wish to load a filename into your iBFT directly.
Were you thinking of customizing the iBFT and parsing it in your initrd?

The gPXE SAN-boot obeys the routing information that gPXE has.  Never
mind which interface(s) DHCP is performed on.  Whichever interface is
the first match for the proper route to the SAN, that'll be the
interface used.

Perhaps you'd be inclined to 'wget' or 'curl' further information from
some instructional server in your initrd in order to setup multiple
paths?

I don't recall just at the moment if the iBFT can have multiple paths in
it.  If you think it can, could you please pass along a reference?
