[gPXE-devel] [PATCH][lkrn] add cmdline and ramdisk support

[Miller, Shao]

Good day Fengguang,

Well thanks to you, developers have more than one option to consider.
Merits of both submissions can be discussed, so perhaps yet another,
better submission can result.

In regards to your "kernel URL root=... initrd URL" preference, the
reason I chose a "cmd=..." approach is because I wished to avoid tying
the gPXE .lkrn prefix to any particular desired boot target type
(bzImage, in this instance).  Lots of people boot to SAN, for instance,
or multiboot images like Xen or VMware.

You are quite right in that a gPXE script as initrd could provide more
than a passed command-line could.  Keeping booting choice parameters all
in one file (syslinux.cfg, grub.conf, etc.) makes for
"one-stop-shopping," though.
