<p align="center"> <strong>Resumo</strong></p>
<p align="left">    O presente trabalho situa-se na área de sistemas operacionais. Quando se tem um conjunto de computadores semelhantes com sistemas instalados independentemente, como em um laboratório, geralmente se tem problemas para realizar a atualização dos arquivos locais, a fim de manter esses computadores com versões coerentes de seus sistemas operacionais e seus diversos programas instalados. Este trabalho apresenta uma solução para este problema, através da centralização da instalação e atualização de sistemas e da implementação de um mecanismo de <em>cache</em> de sistemas de arquivos para disponibilizar essa instalação comum sem a necessidade de reinstalar cada equipamento. No desenrolar dos capítulos são apresentados os trabalhos relacionados, as ferramentas utilizadas para o desenvolvimento do trabalho, a implementação realizada e os principais resultados obtidos.</p>

			<content:encoded><![CDATA[<p>  O SysReq, para quem nunca ouviu falar, é um método &#8220;mágico &#8221; que permite respostar rápidas do kernel Linux através de combinações no teclado. É a mesma tecla do PrintScreen, que até o dia que eu descobri o SysReq, servia para pegar  a tela no Windows.  Seu uso geralmente é relacionado a problemas no micro, quando para tudo e não tem outra solução a não ser o reset !</p>
<p>Por exemplo, a poucos dias o VMware travou minha máquina completamente, por ocupar memória demais (256 Mb para um host virtual, enquanto eu so tenho de RAM 256 !). Então usei o alt+sysreq+k e zap ! Simplesmente morreu tudo que tava na minha frente, funcionou melhor que o &#8220;kill -9 -1&#8243;, que na hora eu não podia digitar.</p>
<p>As principais combinações em um Linux x86 são:</p>
<p>alt+sysreq+h &#8211; help.</p>
<p>alt+sysreq+k &#8211; mata todos os processo no console atual .</p>
<p>alt+sysreq+u &#8211; desmonta e monta todas as partições em modo somente-leitura.</p>
<p>alt+sysreq+s &#8211; sincroniza os sistemas de arquivos, ou seja, escreve tudo que esta pendente no disco.</p>
<p>alt+sysreq+r &#8211; desabilita o &#8220;raw mode&#8221;, o modo do X11.</p>
<p>alt+sysreq+b &#8211; reinicia na hora (perigoso !).</p>
<p>Outras situações em que o SysReq é útil quando trava tudo, tudo mesmo. Basta os comandos alt+sysreq+s (sincroniza tudo) alt+sysreq+u  (desmonta e remonta somente leitura) e alt+sysreq+b (reinicia) e pronto, tudo a salvo.</p>
<p>A única situação que eu presencio, onde o sysreq não funciona mesmo, é em problemas da minha placa de video Trident. Mas pelo que busquei na rede, ela nunca vai funcionar mesmo &#8230;.</p>
<p>Mais detalhes e dicas sobre o SysReq olhem em:</p>
