I'm actually fairly sure this is the same as PR 17223.
I actually suspect there is a heap error somewhere :-(

The 'fs full' message happens because there isn't enough space in the
ramdisk for the core dump. It has nothing to do with the dump being
This is one of the problems that makes debugging this one mighty
If you have a hard reproducible error, it is probably worth trying
hard to track this one down. Unfortunately, all the evidence so far
seems to show that traversing a different route through sysinst causes
the error to go away. No one has found the path that actually
makes it happen. If it is an overwrite, knowing the text/data of the
overwrite might be enough to track it down.

A whole 300k free is far more than it used to be!
Making it larger is slightly tedious, the space has to be allocated
when the kernel is built. Fortunately the blocks of zeros compress
quite well and don't take up that much extra space on the floppies.
