Good.

Hmm, it seems that we can't get the correct stats for / ?
This is from df -a on your system:

# /var/tmp/coreutils-8.23/src/df -a -hl
Filesystem                                                     Size  Used Avail Use% Mounted on
rpool/ROOT/q414                                                   -     -     -    - /
/platform/sun4u-us3/lib/libc_psr/libc_psr_hwcap1.so.1             -     -     -    - /platform/sun4u-us3/lib/libc_psr.so.1
/platform/sun4u-us3/lib/sparcv9/libc_psr/libc_psr_hwcap1.so.1   51G   11G   40G  22% /platform/sun4u-us3/lib/sparcv9/libc_psr.so.1

What do you get from: stat -f /

The next step would be to add a bit of debug to get_fs_usage() in lib/fsusage.c
to see what's being returned there.

thanks,
