Colin Percival 提到了 FreeBSD 12.2 上 autofs 會整合 Amazon EFS，讓掛載進來變得更方便：「Some new FreeBSD/EC2 features: EFS automount and ebsnvme-id」。
用法是先設定 autofs，然後啟用 autofs：
# echo '/efs -efs' > /etc/auto_master # sysrc autofs_enable="YES"
然後重開機後就可以直接切到 /efs/FSID 把 EFS 掛起來了：
Having done this, any access to the path
/efs/FSID(e.g.,/efs/fs-01234567) will automatically and transparently mount that filesystem.
另外加上原來對 EBS 與 ephemeral disk 的支援，這樣 storage 的部份算是該有的都有了：
Using the tool and some devd magic, FreeBSD now maintains a tree under /dev/aws/disk containing the symlinks of the forms
- /dev/aws/disk/ebs/vol-0123456789abcdef
- /dev/aws/disk/linuxname/sdh
- /dev/aws/disk/ephemeral/SERIALNO
