[syslinux] KRNLINUX? CPIOLINUX?

[Shao Miller]

Does anyone think that it might be a worth-while effort to code a 
Syslinux variant which is a "Linux x86 kernel"-format binary and whose 
"initrd" is a simple cpio archive which will comprise the root filesystem?

One can have a disk image with an MBR, partition table, partition, 
filesystem on that partition, SYSLINUX on that filesystem, config-file 
and modules in that filesystem.  One could boot that disk image with 
MEMDISK.  But that doesn't seem as "direct" as booting Syslinux as a 
kernel and providing its root filesystem as an initrd.

One can have an .ISO with an El Torito boot record, an ISO9660 
filesystem, ISOLINUX on that filesystem, config-file and modules in that 
filesystem.  One could boot that disc image with MEMDISK.  But that 
doesn't seem as "direct," either.

The automatic, initrd-building concatenation process that Syslinux 
itself can already do might be handy for building an "initrd" for...  A 
second, booted-to Syslinux.

What do you think?  Use cases available or a waste of time?
