I doubt it is a race condition. If you add sleep command to keep terminal open for some time, sshfs unmounts anyway when terminal is closed.
SSH_ASKPASS is not always usable. Some frontends rely on terminal and assumption that sshfs, like any other mount command, does not need any special treatment. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
