It was also brought to my attention on the mailinglist that the syscall
link() shouldn't return ENOSYS. According to the link(2) the
implementation of link in sshfs should return EPERM to indicate that
creation of links is not supported. However the error check in
sftp-server doesn't check EPERM either.

So actually the proper solution would be to fix this in sshfs and to
add a fix in sftp-server to also check for EPERM.
