mksnap_ffs会清除文件系统的选项
II. Problem Description
The kernel interface for creating a snapshot of a filesystem is the
same as that for changing the flags on that filesystem. Due to an
oversight, the mksnap_ffs(8) command called that interface with only
the snapshot flag set, causing all other flags to be reset to the
default value.
这样会使你的一些设置变成了缺省的,从而引起安全隐患。 |
