        I took a closer look and I see the big discrepancy only in the
numbers that Myth reports, not from "df".  I think it's because of the
way libmyth/util.cpp getDiskSpace divides the number of blocks instead
of the total bytes:

        freespace = statbuf.f_bsize * (statbuf.f_bavail >> 10);
        total = statbuf.f_bsize * (statbuf.f_blocks >> 10);

This can cause the difference to be as much as 1024*(block size
difference).  In my case, the block sizes are 4KB on the local system
and 16KB on the remote system, and the discrepancy is 1024*12KB.
