It has some variation of FFS with logging, which is what I use. Writing
a file as root fails with "no space" when "df" reports about 7000blocks
free. (I have no idea why it stops at around 7000. Something to do with
the log, maybe?)

Anyhow, it doesn't report negative values and all the fields in what
they call "struct statfvs" are unsigned numbers, including bavail.
