You have completed a full ufsrestore of the /(root) file system.
What is the impact of not removing the /restoresymtable?

A.
It would slow down directory lookups.

B.
It would take up disk space unnecessarily.

C.
It would corrupt subsequent uses of ufsrestore.

D.
There is no impact.
It is linked only to the restore that created it and will automatically be deleted.

Explanation:

The purpose of the file is to map inodes on the backed up file system on tape with filenames on the new file system on disk. Once the restore is complete it has no function.
