14.Ar rawdev
15.Sh DESCRIPTION
16.Nm
17is used to install a "first-stage" boot program into the boot area
18of a UFS disk partition, and initialize the table of block numbers the
19.Ar bootxx

28.Ar bootxx
29will use to load
30.Ar ufsboot .

33The arguments are:
34.Bl -tag -width ufsboot
35.It Ar ufsboot
36the name of the second-stage boot program in the file system
37where the first-stage boot program is to be installed.
38.It Ar bootxx
39the name of the prototype file for the first stage boot program.
40.It Ar rawdev
41the name of the raw device in which the first-stage boot program

49.Xr init 8
50.Sh BUGS
51.Nm
52requires simultaneous access to the mounted file system and
53the raw device, but that is not allowed with the kernel
54.Dv securelevel
55variable set to a value greater than zero (the default), so
56.Nm
57only works in single-user mode (or insecure mode - see
58.Xr init 8 ) .
