The df -P command is broken. For example, on this system:

  $ df -Pk /
  Filesystem 1024-blocks Used Available Capacity Mounted on
  /dev/wd0a 4068920 953824 2911656 24% /

  $ df -k /
  Filesystem   1K-blocks       Used      Avail %Cap Mounted on
  /dev/wd0a        508615     119228     363957  24% /

  $ df -Pm /
  df: non-standard block size incompatible with -P

Notice that the amounts are incorrect when using the -P option.

This problem does not happen on a netbsd-4 machine.

I'm quite sure the problem is with -P and not without it. But to be honest,
this is an assumption, as df is my only way of checking this now. And the
-m option to df fails with -P, so -P becomes suspect. df -Pm works on netbsd-4
as it does on other platforms (AIX, Darwin, Linux).

I tested on 2 different netbsd-5 machines and see the same problem.


Try the df command with the -P option.
