Description of problem:
With the default naming scheme of /dev/mapper/VolGroup00-XXX,
filesystem names are too long for normal df output. For example, on my
beta machine I currently have: 

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-RootVol00
                      12901520   5648944   6597216  47% /
/dev/sda1               101086     31750     64117  34% /boot
none                    517016         0    517016   0% /dev/shm
/dev/mapper/VolGroup00-HomeVol02
                       2031952     70888   1857848   4% /home
/dev/mapper/VolGroup00-LocalVol04
                       7063480   4203728   2500944  63% /usr/local
/dev/mapper/VolGroup00-VarVol03
                       2031952    758128   1170608  40% /var

This messes up automated tools that expect df output to be
one-line-per-filesystem, such as the BigBrother monitor or LogWatch
(on by default in RHEL4b2) which shows the nearly useless output:

------------------ Disk Space --------------------

/dev/mapper/VolGroup00-RootVol00
/dev/sda1              99M   32M   63M  34% /boot
/dev/mapper/VolGroup00-HomeVol02
/dev/mapper/VolGroup00-LocalVol04
/dev/mapper/VolGroup00-VarVol03


df should use more intelligent columns to fit it on 80 char if
possible, or perhaps truncate filesystem names unless a --verbose flag
is set. 

Version-Release number of selected component (if applicable):
coreutils-5.2.1-31

How reproducible:
Always

Steps to Reproduce:
1. Install RHEL3b2 with default filesystem names
2. Run df
3. See output
    

Actual Results:  df output split 

Expected Results:  df output one-filesystem-per-line

Use df -P for POSIX format.

'df -P' will resolve this issue for you.
