<h2>Recent -current changes</h2>
|

<ul>
|

<li>The <code>${rcexec}</code> variable used to start daemons with rc.d(8) has been replaced with a more complete rc_exec() function. Handcrafted rc.d(8) scripts must be modified to use this new function: <code># sed -i 's/\${rcexec}/rc_exec/' /etc/rc.d/myscript</code></li>

<li>pkg_add received <a href="https://marc.info/?l=openbsd-cvs&m=165122901325173&w=2">a huge speedup</a> when upgrading, instead of downloading the first bits of each packages to check for update, it uses a local cache embedded in the quirks package</li>

<li>IP forwarding is now faster <a href="https://marc.info/?l=openbsd-cvs&m=165157839007714&w=2">when using multiple CPU</a></li>

<h2>Shell tips</h2>

To improve performance or reduce disk i/o, you can mount /tmp in memory using mount_MFS. The new fstab entry would look like this:
|
||||
</p>
|
||||
<pre> swap /tmp mfs rw,nodev,nosuid,-s=800MB 0 0</pre>
|
||||
In this example, we used 800MB, you should adapt according to how much memory you want for /tmp.

<h3>Note from Solene</h3>
|
||||
<p>
|
||||
This issue is late again. It's hard to find a good publication rate fitting with this hobby work. Originally, I planned to publish every two weeks, that would allow me to gently gather links and material for a new zine, but at the same time there are periods like before a new release during which nothing happen. On the other hand, when waiting long between publications without having a clear deadline, a lot of content need to be covered and it accumulates in a huge pile, which is not necessarily fun to go through.
|
||||
However, while the Webzine is late on schedule, it reached HEIGHT different languages; not all the issues got translated into the height languages but it's been very comforting to meet all the people working on the translations, THANKS!
