{bb} Tweak for error with bb-disk.sh on line 178...

[Tim Meader <tmeader@cne-odin.gsfc.nasa.gov>]

I recently installed BB 1.9e client on a Fedora Core 3 machine. This has 
two drives setup together as a logical volume. Because of this, the default 
name for the device is quite long, ie "/dev/mapper/VolGroup00-LogVol00". 
This causes the standard "df -k" to wrap the info for that device to the 
next line, and thus messes up the parsing for that drive. In addition to no 
longer monitoring that device essentially, it caused an integer comparison 
error on line 178 of bb-disk.sh in /bb/bin. The solution is relatively 
simple: change the $DFCMD to use "df -k -P" instead of "df -k". This 
changes the df to POSIX output, which  displays all info on a single line 
without wrapping. It has the side effect of using the POSIX phrasing for 
the column headers, but since bb-disk.sh doesn't parse the headers anyway 
though, it doesn't matter. Finally I can get my device monitored and not 
fill up my BBOUT file with useless messages either.

Hope this helps others who might be in the same predicament.

I wanted to pass this information on to be included in the next version, 
but I have no idea who to contact about this anymore, or when 1.9f might be 
coming out anyway.
