I'm not familiar with the security of rsync daemons, but I do trust that
of ssh.  I much prefer ssh because it is flexible and works together so
nicely with Linux accounts and file permissions, while the rsync daemon
system tries to reinvent the wheel in these two areas.

When you use SSH, the path on the remote host is interpreted relative to
the home directory of the user as whom you are SSH-ing into the host.
It looks like the remote user has a home directory of / .

Yes!  This is the awesome thing about rsync!  It dovetails with ssh to
provide a powerful, efficient, Internet-transparent copy command.
