该ln命令可以在安装的 Windows 共享上创建硬链接，但cp -al失败。这是预期的行为吗？我试图通过使用cowdancer,rsync和cp -al.
backupuser@lan0:/mnt/backup/share$ mkdir a
backupuser@lan0:/mnt/backup/share$ touch a/b
backupuser@lan0:/mnt/backup/share$ cp -al a x
cp: cannot create hard link `x/b' to `a/b': No such file or directory
backupuser@lan0:/mnt/backup/share$ mkdir x
mkdir: cannot create directory `x': File exists
backupuser@lan0:/mnt/backup/share$ ln a/b x/b
backupuser@lan0:/mnt/backup/share$ ls -l x
total 0
-rwxr-xr-x 0 backupuser backupuser 0 Dec 23 17:33 b
更新：ln实际上是在创建副本而不是真正的链接
