utility is a Bourne shell script which is designed to aid you
|
1999-10-20 07:22:52 +00:00
|
|
|
in updating the various configuration and other files
|
2000-11-14 11:20:58 +00:00
|
|
|
associated with
|
|
|
|
.Fx .
|
1999-10-20 07:22:52 +00:00
|
|
|
It is
|
|
|
|
.Sy HIGHLY
|
|
|
|
recommended that you back up your
|
|
|
|
.Pa /etc
|
|
|
|
directory before beginning this process.
|
|
|
|
.Pp
|
|
|
|
The script uses
|
|
|
|
.Pa /usr/src/etc/Makefile
|
|
|
|
to build a temporary root environment from
|
|
|
|
.Pa /
|
|
|
|
down, populating that environment with the various
|
2000-03-01 14:09:25 +00:00
|
|
|
files.
|
|
|
|
You can specify a different source directory

Add several new features, reorder some code, and continue with the
process of making the script more cross platform friendly.
* Add -i option to automatically install files that do not exist

* Add the ability to specify DESTDIR.
* Allow the user to specify scripts to run right before the

allow the user to specify customized local behavior, and

It then compares each file in that environment
|
2000-03-01 14:09:25 +00:00
|
|
|
to its installed counterpart.
|
|
|
|
When the script finds a
|
1999-10-20 07:22:52 +00:00
|
|
|
change in the new file, or there is no installed
|
|
|
|
version of the new file it gives you four options to
|
2000-03-01 14:09:25 +00:00
|
|
|
deal with it.
|
|
|
|
You can install the new file as is,
|
1999-10-20 07:22:52 +00:00
|
|
|
delete the new file, merge the old and new
|
|
|
|
files (as appropriate) using
|
|
|
|
.Xr sdiff 1
|
|
|
|
or leave the file in the temporary root environment to
|
|
|
|
merge by hand later.
|
|
|
|
.Pp
|
|
|
|
By default it creates the temporary root in
|
|
|
|
.Pa /var/tmp/temproot
|
|
|
|
and compares the
|
|
|
|
.Xr cvs 1
|
|
|
|
version $Id/$FreeBSD strings for files that have them, deleting
|
2000-03-01 14:09:25 +00:00
|
|
|
the temporary file if the strings match.
|
|
|
|
If there is
|
1999-10-20 07:22:52 +00:00
|
|
|
no $Id string, or if the strings are different it
|
2000-03-01 14:09:25 +00:00
|
|
|
compares the files themselves.
|
|
|
|
You can
|
1999-10-20 07:22:52 +00:00
|
|
|
also specify that the script ignore the $Id strings and
|
|
|
|
compare every file.

2000-03-01 14:09:25 +00:00

|

may run into problems without them.

|

it starts the comparison, and after it's done running.
|
|
|
|
The easiest way to handle this is to place the path
|
|
|
|
to the script(s) in the appropriate variables in your
|
|
|
|
.Pa .mergemasterrc
|
|
|
|
file.
|
|
|
|
The script sourced before comparison is named in
|
|
|
|
.Ev MM_PRE_COMPARE_SCRIPT ,
|
|
|
|
and the one sourced after the script is done is
|
|
|
|
.Ev MM_EXIT_SCRIPT .
|
|
|
|
This is the recommended way to specify local modifications,
|
|
|
|
or files that you want to give special handling to.
|
|
|
|
This includes files that you want to be deleted without
|
|
|
|
being compared.
|
|
|
|
Because the named scripts are sourced from within
|
|
|
|
.Nm ,
|
|
|
|
all of the script's variables are available for use in
|
|
|
|
your custom script.
|
2001-03-05 10:13:21 +00:00
|
|
|
You can also use
|
|
|
|
.Pa /etc/mergemaster.rc
|
|
|
|
which will be read before
|
|
|
|
.Pa .mergemasterrc .
|
|
|
|
Options specified on the command line are updated last,
|
|
|
|
and therefore can override both files.

Add several new features, reorder some code, and continue with the
process of making the script more cross platform friendly.
* Add -i option to automatically install files that do not exist
on the system already.
* Add the ability to specify DESTDIR.
* Allow the user to specify scripts to run right before the
comparison starts, and when mm is done. This will
allow the user to specify customized local behavior, and
implement features such as automatically deleting files.
* Document the above changes in the man page.
* Switch to using 'ident' for the CVS Id comparison, which
should help with portability, and makes it faster.
* Reorder, and in one case fix some code by doing things in
ways that make more sense.
* Check to see if the file exists on the system before doing
the comparisons. This saves CPU cycles, and streamlines
the auto-install process.
