用户空间文件系统
From Gentoo Wiki
Filesystem in Userspace (FUSE) provides a way for users to mount file systems without needing special permissions (mounting in Linux is generally reserved to those with administrative privileges).

Emerge
As with most file systems, after building support for the file system into the kernel be sure to install the user space tools:
root #
emerge --ask sys-fs/fuse
Configuration
Files
The following configuration files are available for FUSE:
- /etc/fuse.conf
There are two configuration variables available in the fuse.conf file:
- mount_max - Sets the maximum number of FUSE mounts allowed to non-root users (defaults to 1000 if unset).
- user_allow_other - Allows non-root users to specify the
allow_other
orallow_root
mount options. This is disabled for security reasons.
Usage
Invocation
user $
fusermount -h
fusermount: [options] mountpoint Options: -h print help -V print version -o opt[,opt...] mount options -u unmount -q quiet -z lazy unmount
Mounting filesystems
Use the fusermount command:
user $
fusermount /path/to/mountpoint
Unmounting filesystems
Filesystems can be unmounted using either the umount or the fusermount command:
user $
fusermount -u /path/to/mountpoint
