I'm only interested in the second change ("boot-big.fs shall be removed") 
but couldn't find that in your patch - maybe split this into two seperate 

As for how to handle this: I think it's fine to nuke 
src/distrib/i386/floppies/bootfloppy-big and use what 
src/distrib/i386/cdroms/bootcd offers, but please be aware that there's 
the "iso-image" target in src/etc/Makefile (and esp. 
src/etc/etc.*/ that may still reference this: This is another 
can of worm that needs fixing somehow in the not-so-long run... maybe just 
disable it for i386 and amd64 for now, and point the iso-image target at 
the bootable CDs made for now.

In the long run, the build process needs to be split up better, to allow 
building an install-CD after the install-sets were built - this is 
currently not doable!

(An easy way to have a install-CD already today is by setting 
CDRELEASE=true in the CD Makefiles... I guess I'll commit examples for 
i386 and amd now, really - have a look at 
src/distrib/i386/cdrom/installcd; it requires ' release' being 

To migrate more CDs from the mkisofs-kludge (= src/etc/Makefile's 
iso-image target), more work on makefs(8) needs to be done:

XXX 1) The implementation of this is rather cludgy (copying sets around),
        as our makefs(8) can't put files from multiple directories into
        one image -- something that mkisofs can do with 'graft' points
XXX 2) This should be run after ' release' - It would be nice
        if we had a seperate stage to add such hooks in our build framework
