Hi, Just a question, is there any reason not provide Packages.xz and Contents-<arch>.xz in package repository? I cannot find any information about it, so please tell me.

For fast CPU or narrow bandwidth, xz is good. I think provide Packages.xz rather than bzip2 is better choice (if we can). > henrich@hp:/tmp$ du -k Contents-amd64.* > 24988 Contents-amd64.gz > 15512 Contents-amd64.xz And Contents-<arch>.xz will save disk space and traffic size 10MB x arch (=14) x (stable + testing + unstable) = 420MB/sync -- Regards, Hideki Yamane henrich @ debian.or.jp/org http://wiki.debian.org/HidekiYamane -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
