$HDDDIR/syslinux.cfg
In bootimg.bbclass I have been abstracting out the boot loader so it is
not explicitly referenced. Something like that is in order here. For
example, an EFI boot-directdisk (which admittedly doesn't exist yet)
would not have a syslinux.cfg but would still need the change. Consider
using the syslinux class to abstract this necessary change. Then I can
add the gummiboot change when EFI support is added.
Do you mean adding a function to the syslinux class which updates root=
in syslinux.cfg previously created by build_syslinux_cfg()?
In the words of a wise director at a large technology company, "I meant
whatever is the most intelligent." :-)
This could be a new function in syslinux.bbclass. It could also be a
parameter to build_syslinux_cfg which would allow it to be used from
either bootimg.bbclass, boot-directdisk.bbclass, with or without EFI,
with various kernel versions, etc. I suspect some parameterization will
result in the cleanest, most maintainable approach, but investigation is
required.
Thanks!

Submitted V3 patch which sets SYSLINUX_ROOT appropriately instead of
modifying syslinux.cfg directly.
