删除这些文件系统循环是否安全

我的硬盘上有一些文件系统循环：

$ time for dir in $(df -T | awk "/ext[234]|btrfs/"'{print$NF}' | egrep -vw "/home|/tmp")
do
    sudo /usr/bin/find $dir -xdev -follow -printf ""
done

/usr/bin/find: File system loop detected; ‘/lib/recovery-mode/recovery-mode’ is part of the same file system loop as ‘/lib/recovery-mode’.
/usr/bin/find: File system loop detected; ‘/usr/bin/X11’ is part of the same file system loop as ‘/usr/bin’.
/usr/bin/find: File system loop detected; ‘/usr/share/arduino/hardware/tools/avr/bin/X11’ is part of the same file system loop as ‘/usr/share/arduino/hardware/tools/avr/bin’.
