LPI Certification help and tutorials

For the last couple of days I have been very busy but not too away from my desktop. Though I did not get time to publish anything. Here&#8217;s one of my other favourite distributions. Its known as elpicx. This distribution is oriented towards LPI certification exams and contains some documents and links that are quite helpful.

Good thing is now it supports F9 with KDE.

I found that the documents in the distro are GPL and thus I dont think that there should be any issue in re-distributing the pdfs and the links, so <a href="http://amit.with-linux.com/elpicx/" target="_blank">here it is. If you find anything in these docs or links that I should not link or upload them, let me know. I wil remove them.

Startup animation and theme for Fedora 12 onwards.

Since the release of <a class="zem_slink freebase/en/fedora" title="Fedora" rel="homepage" href="http://fedoraproject.org/">Fedora 12, fedora is using plymouth. Plymouth kicks in just after grub and before the Xserver starts.

Description:

Plymouth provides an attractive graphical <a class="zem_slink freebase/en/bootsplash" title="Bootsplash" rel="wikipedia" href="http://en.wikipedia.org/wiki/Bootsplash">boot animation in
place of the <a class="zem_slink freebase/en/text_messaging" title="Text messaging" rel="wikipedia" href="http://en.wikipedia.org/wiki/Text_messaging">text messages that normally get shown.  Text
messages are instead redirected to a <a class="zem_slink freebase/en/data_logger" title="Data logger" rel="wikipedia" href="http://en.wikipedia.org/wiki/Data_logger">log file for viewing
after boot.
