This wasn't Sun's idea; it dates back at least to 4.2BSD, and possibly earlier.
If it wasn't present in 4.1BSD, it was probably done to avoid the need to make
stand-alone versions of "mkfs" and "restore" for the 4.2BSD file system; V7
(and possibly 4.1BSD) were installed by running a stand-alone "mkfs" and
"restore" to bring in a "dump" of the root file system, and proceeding from
there.
