Rsync vs. cvsup roundup

Vincent Stemen found that it was difficult to get cvsup running on DragonFly, and went looking for mirrors that supplied DragonFly via rsync. Joerg Sonnenberger handily supplied an example script, and Simon ‘codecode’ Schubert supplied a more complex example, though there are more servers that run rsync than just the one in the script. Vincent’s further tests showed better performance with rsync, though Garance A Drosihn pointed out these tests were not comprehensive enough to point out a real advantage. Csup, the cvsup replacement that isn’t dependent on modula-3, is close to working completely as a replacement, though it doesn’t remove the need for cvsupd.
