Portage update.
---------------
  
Portage 2.0.51 continues to be in internal testing. Now in version 
2.0.51_pre13 and masked, it's nearing readiness for ~arch. We'd like to 
cover some changes to Portage that users will notice if they pick up the 
currently masked 2.0.51_pre13, or a later ~arch masked or stable version. 
First of all, due to changes in the Portage cache, users will notice 
corruption messages when performing rsync updates, which will go away when 
the cache is altered in a few weeks. At this point however, versions of 
Portage prior to 2.0.50-r7 will start having problems because they won't 
be able to handle the new cache. As always, users are recommended to read 
the messages from emerge rsync and update Portage whenever a new stable 
version is available. 
 
Also, in the new version /var/cache/edb/virtuals is going to become 
obsolete: Portage will calculate the virtuals based on packages installed 
in the database. Once users upgrade to 2.0.51 the file will be obsolete 
and there will be no need to save it. Also, /var/cache/edb/world will be 
moving to the FHS-compliant state directory, /var/lib/portage. 
 
For more information, read Nicholas Jones[1]'s announcement[2] on 
gentoo-dev.

XFree86, X.org: XDM ignores requestPort setting
-----------------------------------------------
  
XDM will open TCP sockets for its chooser, even if the 
DisplayManager.requestPort setting is set to 0. This may allow authorized 
users to access a machine remotely via X, even if the administrator has 
configured XDM to refuse such connections.

New nvidia Drivers With Support for 2.6 Kernel 
 
Both the Kernel & Hardware and the Gamers & Players forums have threads 
about the new nvidia drivers that have been issued little over a week ago. 
The 4k stacksize problem with 2.6 kernels appears to have been solved, and 
the new drivers feature a configuration utility people seem to be quite 
pleased with: 
 
 * New nVIDIA driver Version: 1.0-6106[8](Kernel & Hardware)

7. Tips and Tricks
==================
  
Using 'make' for backups
------------------------
  
Thanks to Lars Weiler[37] for providing this week's tip.

 37. pylon@gentoo.org
 
Usualy make from sys-devel/make is known as a tool for compiling 
applications. But it could also be used to provide often used commands so 
that they can be accessed easily.
 
Quite everybody wants to do backups. This could be done by packing them 
with tar. For instance, we want to pack the ~/Mail folder and name the 
file with a date:
 
---------------------------------------------------------------------------
| Code Listing 7.1:                                                       |
| tar ~/Mail with date included                                           |
---------------------------------------------------------------------------
|                                                                         |
|$ tar cvjf ~/Backups/Mail-`date +%F`.tar.bz2 ~/Mail                      |
|                                                                         |
---------------------------------------------------------------------------
 
After that we copy that file (and possibly more) to another computer by 
using rsync and delete all the files in ~/Backups afterwards:
 
---------------------------------------------------------------------------
| Code Listing 7.2:                                                       |
| Copy backup-file to another computer with rsync                         |
---------------------------------------------------------------------------
|                                                                         |
|$ rsync -avute ssh ~/Backups/ user@othermachine:~/Backups/               |
|% rm ~/Backups/*                                                         |
|                                                                         |
---------------------------------------------------------------------------
 
And now comes the clue with make. After a week you already forgot the 
commands. Why not store them in a Makefile located in the home-directory, 
so that you only have to call make backup?
 
Inside the Makefile (beware of the uppercased 'M') we provide two targets 
for the commands, so that we can call them separately, e.g. if you only 
want to copy the files. The first target backup will only call the other 
targets in the given order:
 
---------------------------------------------------------------------------
| Code Listing 7.3:                                                       |
| Sample Makefile for backups                                             |
---------------------------------------------------------------------------
|                                                                         |
|backup: compress \                                                       |
|	copy                                                                  |
|                                                                         |
|compress:                                                                |
|	tar cvjf ~/Backups/Mail-`date +%F`.tar.bz2 ~/Mail                     |
|                                                                         |
|copy:                                                                    |
|	rsync -avute ssh ~/Backups/ user@othermachine:~/Backups/              |
|	rm ~/Backups/*                                                        |
|                                                                         |
---------------------------------------------------------------------------
 
Now we can call make backup in the home directory and the ~/Mail-folder 
will be compressed and copied to the other computer. The 
restore-command-set will be your homework ;-)
 
Of course, there is a wide use for batched processes with Makefiles. Think 
about all the things you ever wanted to have scripted with easy usability. 
You can find more instructions in the info make pages.
