Gentoo Weekly Newsletter
This is the Gentoo Weekly Newsletter for the week of March 22nd, 2004.
1. Gentoo News
Security-only updates and stackable profiles
This week, two features on the 2004.1 Feature Request List[1] were added 
to Gentoo. 

The first, a feature often requested by users, is security-only updates. 
Until now, emerge -u world was the only choice for users who wanted to 
update their system in one fell swoop. While useful to many users, others 
didn't want to keep up with all of Gentoo's high-pace release cycles, and 
only wanted to install security-related updates, having to scan the 
security updates every now and then to do so. Now glsa-check, part of the 
gentoolkit automates this process. Users can now use this command to 
automatically update the system with security-related updates only. Please 
note, however, that this tool is completely new and meant to test the 
functionality before it is propagated into Portage itself. For more 
information, read the Portage GLSA Integration Document[2]. 

The other improvement was made under the hood, and won't change Gentoo's 
functionality or the way most users interact with the system, but succeed 
in decreasing the distribution's bloat. This new feature is the addition 
of stackable profiles. Historically, Gentoo has used profiles, residing in 
/usr/portage/profiles to describe the system; the most commonly used have 
been default-x86-1.4 and default-x86-2004.0. Profiles contain a set of 
packages that every Gentoo system using the profile in question should 
have installed, a set of mappings from virtual packages to their default 
packages, and a mapping of packages that provide various USE flags once 
installed. However, it was noticed that these profiles had significant 
overlap between them, so cascading (or stackable) profiles were 
implemented. For more information, read the Gentoo Cascading/Stackable 
Profiles Document[3]. 

2. Gentoo Security
Multiple OpenSSL Vulnerabilities
Three vulnerabilities have been found in OpenSSL via a commercial test 
suite for the TLS protocol developed by Codenomicon Ltd. 
For more information, please see the GLSA Announcement[4] 

3. Heard in the Community
Cloning Linux Machines
Have a need to create many identical Linux machines? One poster on the 
gentoo-user list did.Read here[5] for some usefuladvice on doing a mass 
Linux rollout.

Compiling java programs.
As java should (theoretically at least) create identical binaries on the 
same desktops, why are we distributing them as source as opposed to 
binaries? Well this was the question asked here[6] this week. Cruise on 
over for a couple of reasons why and why not. 

4. Bugzilla
 * Statistics 
 * Closed Bug Ranking 
 * New Bug Rankings 
The Gentoo community uses Bugzilla ([7]) to record and 
track bugs, notifications, suggestions and other interactions with the 
development team. Between 12 March 2004 and 18 March 2004, activity on the 
site has resulted in: 

 * 577 new bugs during this period 
 * 333 bugs closed or resolved during this period 
 * 13 previously closed bugs were reopened this period 
Of the 5337 currently open bugs: 126 are labeled 'blocker', 207 are 
labeled 'critical', and 435 are labeled 'major'. 
Closed Bug Rankings
The developers and teams who have closed the most bugs during this period 
 * Jeremy Huddleston[8], with 26 closed bugs[9]  
 * Java Team[10], with 25 closed bugs[11]

5. Tips and Tricks
Using ulimit
This week's tip introduces ulimit -- a command to define system resource 
limits. As a user, you can create self-imposed limits to prevent processes 
from taking up too much CPU time or memory.
To view all available resource limits, type ulimit -a. This command shows 
the limits the system administrator has imposed on your account. You can 
lower these limits, but you can't increase them. Many accounts will have 
'unlimited' listed. If so, here are some useful things you can do with 
| Code Listing 5.1:                                                       |
| Preventing core files                                                   |
|                                                                         |
|% ulimit -c 0                                                            |
|                                                                         |
| Code Listing 5.2:                                                       |
| Preventing Files larger than 25 MB                                      |
|                                                                         |
|% ulimit -f 25600                                                        |
|                                                                         |
Since ulimit is a builtin shell command, see your shell manual page for 
more information (e.g. man bash, man zsh, etc.).
Note:  System administrators can impose system-wide limits using 
/etc/limits. See man limits for more information.
