Sorry, it means Linux.conf.au (Australia): http://lca2007.linux.org.au/ Jan. 15-20, 2007 > I don't know that acronym, but if you ask me when it should happen: > _Before_ the next big thing is released, e.g. before 2.6.20-final. > Reason: You never know how long they're chewing [downloading] on 2.6.20. > Excluding other projects on kernel.org from my hypothesis, I'd suppose the > lowest bandwidth usage the longer no new files have been released.
