[arch-general] Adopt tar.xz for official repo packaging ?

Corrently Archlinux uses a tar+gzip combination and it works nicely. But right now there's a stable lzma compression available using "tar Jcvf", which could create much smaller packages and still fast decompressions. (of course you need to have xz-utils) think about all the bandwidth that could be saved ! my little experiment shows kernel26-2.6.30-5-x86_64.pkg.tar.gz coreutils-7.4-1-x86_64.pkg.tar.gz tar.gz 35338866 (100%) 4853937 (100%) tar.xz 24892732 (70.4%) 1843592 (38.2%) i guess one of the major concerns is that tar & gzip is more common than xz. but since GNU is also packing their coreutils in xz packs, i guess that a good time to switch?
