Linux Questions

["Joe Marchak" <j_marcha@example.com>]

I have a few basic questions on Linux:

1)  Why do a lot of symbolic links go from /usr to /var and back again?  For
instance,
    to set zoneinfo to Japan, the symbolic link goes from
/usr/lib/zoneinfo/localtime to 
    /var/lib/zoneinfo/localtime, which is linked back to
/usr/lib/zoneinfo/Japan.  This 
    seems awkward, but there must be a reason for it.

2)  In BSD, it is possible to use the "top" utility to see the most used
processes.
    Top is available for linux, but running it always gives a floating point
exception.
    (at least on three systems I've tried).

3)  What are the ATTRIB.BND files for that are attached to some of the e-mail
    messages that are sent out? 

Thanks!
