Even base system uses such files :-)

$ ls -lsk /etc/pwd.db
140 -rw-r--r--  1 root  wheel  159744 21 ÉÀÎ 12:26 /etc/pwd.db
$ file /etc/pwd.db
/etc/pwd.db: Berkeley DB 1.85 (Hash, version 2, native byte-order)

File occupies 140K = 143360 bytes and its length is 159744 bytes,
so it has to be sparse. FreeBSD 4.11-STABLE.
