Granted I'm open and willing to suggestions to make that happen on the "#CoreEdition" of OS/1337 but as of now that'll be the limit.
Tho this could change later once #syslinux has been replaced with something more efficient...
I guess @landley may also be interested in the alternatives to syslinux for #mkroot / #toybox?

Either way, development is continuing and work is in progress...
