To all of these suggestions, I'd like to point out that if you're willing to pay the same cost in administration (maintaining a separate filesystem for /usr/portage), then you can have EVERYTHING in the advantages list, and none of the things in the disadvantages list by simply using a small reiserfs space for /usr/portage, with tail-packing enabled.
For the rsync.g.o main rotation servers, we actually do that, just RAM-backed to serve files as fast as possible without hitting disk. When you removed bandwidth limitations and disk limitations on the client side, I believe the record time for a emerge --sync that was 24 hours out of date was somewhere around 23 seconds. If you really wanted to get the rsync transfer size down, see what you can do about the 'file list size' section, which is eating up a lot of the download gains with the classical rsync:// sync. -- Robin Hugh Johnson Gentoo Linux Developer & Infra Guy E-Mail : [email protected] GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
