Building local repo - eliminating dups - why some new x86_64?

["David C. Rankin, J.D.,P.E." <drankinatty@xxxxxxxxxxxxxxxxxx>]

Listmates,

	I'm building a local repo for boxes to update via the lan instead of 
redownloading. I have my repo on my local server as:

arch/
    x86/
    x86_64/

	I have moved all files for my two x86_64 boxes to the arch/x86_64 dir and I 
am filtering with a script to eliminate dups by moving the lesser numbered 
packages to arch/x86_64/oldpkgs. Testing the script before the actual move of 
packages, I ran across this anomaly in some filenames: (script output) [1]

<snip>


ttf-isabella-1.003-3.pkg.tar.gz -> oldpkgs
ttf-isabella-1.003-4-x86_64.pkg.tar.gz

tunepimp-0.5.3-5.pkg.tar.gz -> oldpkgs
tunepimp-0.5.3-6-x86_64.pkg.tar.gz

tzdata-2009f-1-x86_64.pkg.tar.gz -> oldpkgs
tzdata-2009g-1-x86_64.pkg.tar.gz

unrar-3.8.5-2-x86_64.pkg.tar.gz -> oldpkgs
unrar-3.9.1-1-x86_64.pkg.tar.gz

<snip>

	As shown above, there are multiple packages where the earlier version did 
*not* contain the x86_64 designation where the current package now does. Are 
these the same packages? If so why did earlier packages not have the x86_64 
and when was the architecture added? Are all packages now going to have the 
architecture specified?

Footnotes:

[1] Filtering done by a simple look ahead and the output created as follows:

PKGFILES=( $(ls -1 /home/backup/archlinux/x86_64) )
for ((i=0;i<${#PKGFILES[@]}-1;i++)); do
	if [[ ${PKGFILES[$i]%%-[[:digit:]]*} == ${PKGFILES[$i+1]%%-[[:digit:]]*} ]]; 
then
		echo -e "${PKGFILES[$i]} -> oldpkgs\n${PKGFILES[$i+1]}\n"
	fi
