.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility performs post-installation checks and/or fixes on a system's
|
|
configuration files.
|
|
It is especially useful after system upgrades, e.g. after updating
|
|
from
|
|
.Nx 1.6.2
|
|
to
|
|
.Nx 2.0 .
|
|
The items to check or fix are divided in two groups: enabled by
|
|
default and disabled by default.
|
|
The latter are items that are dangerous for some reason, for example
|
|
because they remove files which may be still in use.
|
|
If no
|
|
.Ar items
|
|
are provided, the default checks or fixes are applied.
|
|
Those which are disabled by default must be provided explicitly.
|
|
.Pp
|
|
Supported options:
|
|
.Bl -tag -width XsXsrcdirXXX -offset indent
|
|
.It Fl a Ar arch
|
|
MACHINE_ARCH.
|
|
Defaults to machine of the host operating system.
|
|
.It Fl d Ar destdir
|
|
Destination directory to check.
|
|
Defaults to
|
|
.Pa / .
|
|
.It Fl m Ar machine
|
|
MACHINE.
|
|
Defaults to machine of the host operating system.
|
|
.It Fl s Brq Ar srcdir | Ar tgzdir | Ar tgzfile
|
|
The location of the reference files, or the
|
|
.Nx
|
|
source files used to create the reference files.
|
|
This may be specified in one of three ways:
|
|
.Bl -tag -width XXsXtgzfileXX
|
|
.It Fl s Ar srcdir
|
|
The top level directory of the
|
|
.Nx
|
|
source tree.
|
|
By default this is
|
|
.Pa /usr/src .
|
|
.It Fl s Ar tgzdir
|
|
A directory in which reference files have been
|
|
extracted from one or more of the
|
|
.Dq Pa etc.tgz
|
|
or
|
|
.Dq Pa xetc.tgz
|
|
files from a binary distribution of
|
|
.Nx .
|
|
.It Fl s Ar tgzfile
|
|
The location of one or more set files
|
|
(or
|
|
.Dq "tgz files" )
|
|
from a binary distribution of
|
|
.Nx .
|
|
Each set file is a compressed archive containing reference files.
|
|
More than one set file may be specified, either by
|
|
using a single
|
|
.Fl s
|
|
option with a colon-separated list of
|
|
.Ar tgzfile
|
|
names, or by using multiple
|
|
.Fl s
|
|
options; this is likely to be useful to specify the locations of both the
|
|
.Pa etc.tgz
|
|
and
|
|
.Pa xetc.tgz
|
|
set files.
|
|
Note that file names may not contain embedded colon
|
|
.Pq Ql \&:
|
|
characters, because that would conflict with the use of the colon
|
|
character to delimit multiple file names with a single argument.
|
|
.El
|
|
.El
|
|
.Pp
|
|
The
|
|
.Ar operation
|
|
argument may be one of:
|
|
.Bl -tag -width usageXX -offset indent
|
|
.It Cm check
|
|
Perform post-installation checks on items.
|
|
.It Cm diff Op Xr diff 1 options
|
|
Similar to
|
|
.Cm check ,
|
|
but also show the differences between the files.
|
|
.It Cm fix
|
|
Apply fixes that
|
|
.Cm check
|
|
determines need to be applied.
|
|
Not all items can be automatically fixed by
|
|
.Nm ,
|
|
and in some cases an error will be reported,
|
|
after which manual intervention will be required.
|
|
.Pp
|
|
Conflicts between existing files in the target file system
|
|
and new files from the
|
|
.Nx
|
|
distribution are resolved by replacing the existing file
|
|
with the new file; there is no attempt to merge the files.
|
|
See
|
|
.Xr etcupdate 8
|
|
for an alternative update method that is able to merge files.
|
|
.It Cm help
|
|
Display a short help.
|
|
.It Cm list
|
|
List available
|
|
.Ar items ,
|
|
showing if they are enabled or disabled by default.
|
|
.It Cm usage
|
|
Same as
|
|
.Cm help .
|
|
.El
|
|
.Sh EXIT STATUS
|
|
The
|
|

|
|
utility exits 0 on success, and \*[Gt]0 if an error occurs
|
|
or a problem was found.
