Re: [SLUG] making boot floppy 'no space left'
Effectively the mkbootdisk command builds the image in temp disk space then uses 'dd' (or cp?) to write to the floppy device. If either there's not enough space in /tmp or the floppy isn't formatted ok you're going to have problems. If /tmp is full firstly try deleting stuff then try creating /home/tmp with same permissions then mv /tmp /tmp.old; ln -s /home/tmp /tmp You're probably going to need at least half a meg of temp space before it does the compression. It looks more like the target system didn't have enough space. This usually means the floppy needs reformatting. man fdformat eg: fdformat /dev/fd0H1440 - frequently I find failures because a) the floppy drive is old/dirty/disused and secondly the media has been laying around gathering dust. Before you start, flip the drive door open and blow air into it to dislodge dust. Manually inspect the media for crap inside the jacket - it can damage the drive too. Did I mention I hate floppy drives?

Re: [SLUG] making boot floppy 'no space left'
I think you will find that mkbootdisk is trying to write to a file which is basically a loop-mounted filesystem the size of the target floppy. Unfortunately I think your kernel is far too big to write to a floppy. You will need to create a minilmal kernel first to write to a floppy. (Unfortunately making boot floppies is pretty much old magic that I have forgotten - if I need a boot floppy this days I look for the one's supplied standard by most distros). Googling for mkbootdisk no space comes up with a number of links that have faced the same issue as yourself.

Your error message does not say disk full although that may come to pass, it does say after 20 sectors there was an error. Maybe 50% of 'reputable brand' floppies in a good drive will work. These days use a CD rom, usb flash, anything but a floppy.
