Also there is some inconsistency in how specified units are handled pb-laptop:~$ BLOCKSIZE=1K df . Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda5 5034364 4815560 167700 97% / pb-laptop:~$ BLOCKSIZE=K df . Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda5 5034364K 4815560K 167700K 97% / pb-laptop:~$ BLOCKSIZE=Ki df . Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda5 5034364 4815560 167700 97% / pb-laptop:~$ BLOCKSIZE=KiB df .

I think (2) is a good option. Though in saying that, supporting this isn't that important I think, as the relative sizes are what's important given that the values are truncated in any case. So I'm 50:50 about making that change. cheers, Pádraig.
