No, there is no free space on the flash drive of any significance, and
certainly not enough for a large package like cups. Also, when running
without having unslung to an external disk or flash device, the /var
partition is coming from the internal RAM -- so the lack of available space
is compounded by an effective reduction in the amount of memory available
for cups. Also note that there is a failure mode associated with the type
of filesystem used on the internal flash -- basically, it requires at least
on free flash block that it can erase in order to do a delete operation. So
if you are not lucky, it is rather easy to fill up the internal flash to the
point where you cannot add anything more, but it is also too full to delete
anything -- when you get in this situation, you must reflash the device
The "no disks attached" mode of operation with Unslung is intended only for
diagnostics and repair, and initial setup. If you need an "everything in
the internal flash" mode of operation, you should take a look at the OpenWRT
distribution for the NSLU2, which offers more space and generally better
support for such a "internal-flash-only" operation mode.

device, where such detail is not necessary. Checking the size of the ipkg
file itself is usually adequate.
My local office supply store is selling 512MB flash disks for under 10
USD -- that takes care of the free space problem completely. And for that
kind of price, you don't even have to worry about turning off swapping to
reduce wear on the external flash device!
