The first paragraph of that URL mentions sftp, "SSHFS normally
propagates the umask of the client to the server. This works great
when the sftp server doesn’t care about the umask while creating files
or directories. But the problem is, that the openssh sftp server
indeed cares about the server side umask", so I checked the sshfs man
page and it says "On the remote computer the SFTP subsystem of SSH is
used". You should therefore be able to set the umask for sftp via the
usual wrapper script and get the umask that you want.
