.Sh NAME
.Nm dset
.Nd "update the boot file to the current configuration"
.Sh SYNOPSIS
.Nm dset
.Op Fl vqt
.Sh DESCRIPTION
.Nm Dset
records the configuration changes for ISA devices that have been made
from
.Em UserConfig
after booting with the
.Fl c
option. The changes (if any) are recorded to the file name returned by
.Xr getbootfile 3 .
.Nm Dset
is typically called from within
.Pa /etc/rc .
.Pp
.Nm Dset
understands the following options:
.Bl -tag -width indent -compact
.It Fl v
Verbose; tell what is being done.
.It Fl q
Quiet; don't print any error messages.
.It Fl t
Test only; don't actually record any changes to the boot file, print
only what would have been done. This implies
.Fl v .
.El
.Sh DIAGNOSTICS
The
.Nm
utility exits with status 0 on success, or with status 1 if any
problem occurred. Unless
.Fl q
has been specified, a short message hinting to the cause of the problem
will be printed to standard error output.
.Sh SEE ALSO
.Xr getbootfile 3 ,
.Xr boot_i386 8 ,
.Xr rc 8
.Sh HISTORY
The
.Nm
command appeared in
.Fx 2.0.5 .
