Dropbox を FUSE mount 出来る dbxfs というものを見つけたので試してみました．
Doropbox の Linux client はファイルシステムがext4のみと制限されます．dbxfs であればおそらくこの制限も問題ないのではないかと思います．(未確認)
The Dropbox folder will need to be on an ext4-formatted hard drive or partition
Note: ecryptfs is not supported, but Dropbox will continue to sync with supported file systems that are encrypted via full disk encryption (e.g. LUKS)
導入
$ sudo apt install libfuse2 python3-pip
help
$ ~/.local/bin/dbxfs -h usage: dbxfs [-h] [-f] [-v] [-s] [-n] [-l SMB_LISTEN_ADDRESS] [-c CONFIG_FILE] [-e ENCRYPTED_FOLDERS] [--print-default-config-file] [mount_point] positional arguments: mount_point optional arguments: -h, --help show this help message and exit -f, --foreground keep filesystem server in foreground -v, --verbose show log messages, use twice for maximum verbosity -s, --smb force mounting via SMB -n, --smb-no-mount export filesystem via SMB but don't mount it -l SMB_LISTEN_ADDRESS, --smb-listen-address SMB_LISTEN_ADDRESS address that SMB service should listen on, append colon to specify port -c CONFIG_FILE, --config-file CONFIG_FILE config file path -e ENCRYPTED_FOLDERS, --encrypted-folder ENCRYPTED_FOLDERS relative paths of encrypted folders, can be used multiple times. requires safefs --print-default-config-file print default config file path to standard out and quit
初回mount
$ ~/.local/bin/dbxfs ~/fuse/dbxfs We need an access token. Perform the following steps: 1. Go to https://www.dropbox.com/oauth2/authorize?response_type=code&client_id=vinkudorurc8kno 2. Click "Allow" (you may have to log in first) 3. Copy the authorization code. Enter authoritization code (Ctrl-C to quit): NodigIOndefkiwitshOrackazEuweavirtyedCibEdI We're all connected.

- のurl をブラウザで開いて認証を行う
認証後の画面で cli-dbxfs のアクセスを許可する．
許可後に表示されるトークンを 3. の後ろにコピー&ペーストする．

次回以降のために資格情報を保存するか? - Would you like to help us improve dbxfs by providing anonymous error reports?
匿名のエラー報告を行いdbxfsに改善の支援を行うか? - Mount point “/home/matoken/fuse/dbxfs” doesn’t exist, do you want to create it?
マウントポイントが存在しないので作成するか?
マウント確認
$ ls ~/fuse/dbxfs/
アンマウントする
$ fusermount -u ~/fuse/dbxfs
資格情報を保存していた場合2回目以降のマウントは何も聞かれない
$ ~/.local/bin/dbxfs ~/fuse/dbxfs

アクセストークンをpgpファイルに格納することも出来るようだが手元の環境では未だうまく行っていない(多分何か勘違いをしている) EDIT: やはり使い方が間違っていた．次の記事に書いた -> Dropbox を FUSE mount する dbxfs のアクセストークンを gpg で暗号化する – matoken’s meme 設定ファイルの場所確認

持ち運びモバイルPCだと辛いでしょうが，据え置きデスクトップ環境などのオンラインのマシンでは便利そうです．
