That's the right idea, but rsync relies on the getpw* functions of the C library rather than reading /etc/passwd directly, so the fix wouldn't be as simple as adding an option to use a different path to /etc/passwd. What you can do that works right now is pull from an rsync daemon configured to chroot into the backup so that the daemon's calls to getpw* access the /etc/passwd file inside the chroot. Matt
