如何使用mount（8）和fstab注册FUSE文件系统类型？ [英] How to register FUSE filesystem type with mount(8) and fstab?

问题描述

我已经写了一个小型的基于FUSE的文件系统，现在唯一缺少的部分就是我想用fstab（5）注册它，以便在系统启动时自动挂载它，并且/或者手动挂载 mount / srv / virtual-db 。我知道，我可以运行 /usr/bin/vdbfs.py / srv / virtual-db

对不起，因为这可能不完全是一个编程问题，但它是高度相关的，因为打包和部署仍然是程序员的工作。通常，通过创建一个新的挂载文件系统类型，注册一个新的挂载文件系统类型一个可执行文件 mount.fstype 。

 
 $ ln -s / usr / bin / vdbfs.py /usr/sbin/mount.vdbfs 
 

如果 vdbfs.py 需要 mount -ish参数（即 dev path [-o opts] ），然后 mount -t vdbfs 并使用 vdbfs 作为 fstab 中的第三个字段。如果没有的话，你可以创建一个包装器，它包含了这个表单的参数，并将它们映射到你的 vdbfs.py 所需的任何地方。

FUSE还应该安装 mount.fuse 可执行文件; mount.fuse'vdbfs.py＃dev'path -o opts 将继续并调用 vdbfs.py dev path -o opts 。在这种情况下，可以使用 fuse 作为文件系统类型，并在 vdbfs.py＃ p>

I've written a small FUSE-based filesystem and now the only part's missing is that I want to register it with fstab(5) to auto-mount it on system startup and/or manually mount it with just mount /srv/virtual-db. How can I achieve this?

I know, I can just run /usr/bin/vdbfs.py /srv/virtual-db from some init script, but that's not exactly pretty.

I'm sorry because this may be not exactly a programming question, but it's highly related, as the packaging and deployment is still the programmer's job.

解决方案

In general, one "registers" a new mount filesystem type by creating an executable mount.fstype.

$ ln -s /usr/bin/vdbfs.py /usr/sbin/mount.vdbfs

If vdbfs.py takes mount-ish arguments (i.e. dev path [-o opts]), then mount -t vdbfs and using vdbfs as the 3rd field in fstab will work. If it doesn't, you can create a wrapper which does take arguments of that form and maps them to whatever your vdbfs.py takes.

FUSE should also install a mount.fuse executable; mount.fuse 'vdbfs.py#dev' path -o opts will go on and call vdbfs.py dev path -o opts. In that case, you can use fuse as your filesystem type and prefix your device with vdbfs.py#.
