If no directory is specified, the .Dq Pa /dev directory is used. .Pp Keys are a structure containing a mode_t followed by a dev_t, with any padding zero'd out. The former is the type of the file (st_mode & S_IFMT), the latter is the st_rdev field. .Pp The options are as follows: .Bl -tag -width indent .It Fl c Create a .Xr db 3 database for compatibility with libc versions and statically linked programs from before .Nx 6.0 .
