sshfs 2.x unable to create mount points (Sierra/High Sierra and later)

[matt-hammond-bbc (Matt Hammond)]

A change in Mac OS Sierra and later has locked down permissions on /Volumes such that it is not possible to create mount points without root privileges. Request that this port be updated to sshfs 3.x to resolve this.

The security changes to Sierra and later: ​https://derflounder.wordpress.com/2016/09/21/macos-sierras-volumes-folder-is-no-longer-world-writable/

osxfuse 3.5.0 added support to automatically create mount-points, but sshfs also needed changes to stop it checking that the mount-point already exists. This change has been made to the 3.x branch, but not the 2.x branch.

Example (running High Sierra 10.13.6 with:

• sshfs @2.10_0
• osxfuse @3.8.2_0

  $ sshfs user@SERVER:/ /Volumes/XXXX -oreconnect,volname="SERVERNAME",idmap=user
  mount: realpath /Volumes/XXXX: No such file or directory
