different 'sum' on three different FC3 installs

[Mark Hittinger]

Hi

I ran into something curious.  I installed FC3 on three computers with the
same set of CD's and updated them with yum roughly at the same time.

Afterwards I noticed that certain system binaries (for example /bin/csh and
/bin/login) all have different 'sum' checksums on the three systems.
The file sizes are the same.

Historically this has meant bad things but I'm starting to suspect that FC3
is doing this on purpose.

Can anyone provide a pointer or an explanation of this behavior?
