сбои snapd для запуска с sshfs монтируются в fstab

Идентификатор дистрибьютора: Описание Ubuntu: Ubuntu 16.04.4 Выпуск LTS: 16.04 Кодовое название: гостеприимный

Последней версии snapd не удается запуститься, если/etc/fstab содержит sshfs, монтируются.

sshfs#ftpUser@server.domain.com:/home/jail/user/files/ /media/mediadrive fuse defaults,_netdev,uid=1000,gid=1000,allow_other,port=22,reconnect,IdentityFile=/home/user/.ssh/id_rsa_ftpUser 0 0

snapd бросает следующие ошибки в/var/log/syslog

Комментирование sshfs строки позволяет snapd запускаться. Как это может быть разрешено?
