Hi Adam,

That is a faked value.
It is impossible to know the amount of free or occupied space on Coda -
both are infinite.

In contrast, under Linux "df /coda" shows the state of the local cache,
which is very handy, though confuses some programs who want to check
available space, as low space _in_cache_ does not mean you can not store
a lot :)

The faked free space trick appeared first in AFS, I think.

You can get some storage-related information _per_volume_
by doing "cfs lv /coda/path/......", but not via "df".
