Yeah - data space.  Try df -i and see if maybe you aren't really low on
inodes. :-)  (If you get that error and df -i says you have more than a
few inodes left, There Is A Bug - I say "more than a few" rather than
"any" because there may be temporary files or the like.)

Data blocks left (what df shows you without -i) has *nothing* to do
with inodes left, at least not for ffs (or any other local filesystem
type that supports writes AFAIK).  The total number of inodes is fixed
at filesystem create time; the only way to change it is to remake the
filesystem.  (Almost.  I did take a stab at writing a filesystem
resizer, but even if I had it working, it isn't designed to change
inode counts without resizing the filesystem).

If you'll never need that much VM.  Your total available VM is total
RAM + total swap (roughly - it's actually a little less because various
things steal some RAM for overhead, but if you're talking gigs, the
overhead is down in the noise).

Unless you're running some king hell huge programs you should be fine.
("A gigabyte here, a gigabyte there, pretty soon you're talking serious
memory usage." :-)
