According to sys/ddb/db_command.c,
the first one is db_show_all_mount() (was added in 2019) and
the second one is db_mount_print_cmd() (was added in 2003).

What is the right situation?

(By the way, I have tried to split them into two commands, but
the second one, db_mount_print_cmd() looks to cause an address error
in m68k)

>How-To-Repeat:
Enter ddb.

I don't have.
