allow_root
为什么root没有设置时可以看到用户文件fuse
? (user2 获取permission denied
,ls /media/user1/Data
但可以通过sudo
Linux Mint 19 查看文件)。
user2@PC:~$ cat /etc/fuse.conf
...
# Allow non-root users to specify the allow_other or allow_root mount options.
#user_allow_other
user2@PC:~$ mount
...
/dev/sda5 /media/user1/Data fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0
user2@PC:~$ man fuse
...
allow_other
This option overrides the security measure restricting file access to the user
mounting the filesystem. So all users (including root) can access the files. This
option is by default only allowed to root, but this restriction can be removed with
a configuration option described in the previous section.
user2@PC:~$ ls /media/user1/Data
ls: cannot access '/media/user1/Data': Permission denied
user2@PC:~$ sudo -i
# ls /media/user1/Data
...list of files
