  script_tag(name:"insight", value:"Mounted filesystems can have a variety of flags set on them.  Some
flags affect performance and reliability, while others enable or
disable particular security-related features such as the ability to
execute a binary stored on the filesystem or the use of access control
lists to complement normal Unix file permissions.

The mksnap_ffs(8) command creates a `snapshot' of a filesystem.  A
`snapshot' is a static representation of the state of the filesystem
at a particular point in time.  Snapshots have a variety of uses,
but their primary purpose is to make it possible to run fsck(8) and
dump(8) on live filesystems.

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.");
