			<content:encoded><![CDATA[<p>Avete dei file importanti da backuppare tipo file di configurazione, documenti, foto, ecc??</p>
<p>Bene, senza ricorre a softwares vari ed eventuali vi scrivo un piccolo trucco per salvare i vostri files:</p>
<p>Anzitutto creiamo un file, per esempio, in /home/$user/$nomebackup.conf</p>
<p style="padding-left:30px;"><code>touch /home/$user/$nomeback.conf</code></p>
<p>Poi scriviamo dentro questo file i files che vogliamo salvare, per esempio:</p>
<p style="padding-left:30px;"><code>ls /etc/rc.conf &gt;&gt; /etc/$nomebackup.conf</code></p>
<p style="padding-left:30px;"><code>ls /home/$user/foto.jpg &gt;&gt; /etc/$nomebackup.conf</code></p>
<p style="padding-left:30px;"><code>ls /etc/ddclient.conf &gt;&gt; /etc/$nomebackup.conf</code></p>
<p>Finito di scrivere i nostri files è arrivato il momento di fare il backup vero e proprio<strong>:</strong></p>
<p style="padding-left:30px;"><code>tar -cjvpf backup-`date +%d-%m-%Y`.tar.bz2 -T /etc/backup.conf<br />
</code></p>
<p>(<strong>NB: il comando va tutto sulla stessa riga, prima di <em>date</em> <span style="text-decoration:underline;">NON</span> c&#8217;è una virgoletta normale come questa &#8216; ma c&#8217;è un accento grave `)</strong>:</p>
<p>Con quel comando ho detto a tar di:</p>
<p><strong>c</strong>: crea un nuovo archivio</p>
<p><strong>j</strong>: crealo in bz2</p>
<p><strong>f</strong>: files</p>
<p><strong>v</strong>: verbose, ovvero fammi vedere quello che fai</p>
<p><strong>p</strong>: conserva i permessi dei files</p>
<p><strong>T</strong>: leggi files da backuppare da file di input</p>
<p>inoltre usando la dicitura <em>backup-<em>`</em>date +%d-%m-%Y` </em>all&#8217;archivio di nome <em>backup</em> sarà aggiunta la data di oggi in formato giono-mese-anno.</p>
<p>Per <strong>ripristinare</strong> il backup dobbiamo invece dare questo comando:</p>
<p style="padding-left:30px;"><code>tar -xvpjf $nome-$data.tar.bz2 -C /$percorso-estrazione</code></p>
<p>dove il comando <em>x</em> estrae i file nell&#8217;archivio, il comando <em>-C </em>serve per spostarsi nella directory in cui ci interessa sia estratto l&#8217;archivio e gli altri comandi sono riportati li sopra <img src='http://s2.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Qualche giorno fa è stata aggiornata libpng dalla versione 1.2.44 alla versione 1.4.3&#8230;bene, update andato a buon fine!</p>
<p>Spengo e vado a nanna.</p>
<p>Un paio di giorni dopo, mentre aggiornavo i codec gstreamer, un errore mi ha insospettito: <em>gst-plugins-pango</em> non compilava a causa di un problema con <em>libpng12</em>.</p>
<p>Vabbè dico, diamo un bel <em>revdep-rebuild </em>e tutto si sistema&#8230;sè&#8230;credeteci voi (pure io ci speravo <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' />  )&#8230;</p>
<p>Devono essere <em>riemersi </em><strong>60 pacchetti</strong>&#8230;un&#8217;infinità per il mio <em>eeepiccolo</em> ma io non dispero, tanto non dovevo usarlo e poteva macinare tranquillamente&#8230;&#8230;&#8230;&#8230;..</p>
<p>Così dopo circa 2 ore e 15 minuti, al pacchetto 53/60, <em>compiz-plugins-extra </em>decide di darmi errore, sempre a causa di libpng12&#8230;ARGH! <img src='http://s0.wp.com/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' /> </p>
<p>Cerco un po&#8217; in giro&#8230;e trovo <a href="http://blog.flameeyes.eu/2010/06/29/stable-users-libpng-update" target="_blank">QUESTA</a> soluzione che mi ha illuminato la via <img src='http://s2.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p><strong>Premessa 1:</strong> installare lafilefixer con emerge, ovvero: <em>emerge lafilefixer</em></p>
<p><strong>Premessa 2: </strong>bisogna editare un file, precisamente <em>/etc/portage/bashrc</em></p>
<p style="padding-left:30px;"><code>post_src_install() {<br />
lafilefixer "${D}"<br />
}</code></p>
<p>Poi bisogna compiere questi passaggi:</p>
<p style="padding-left:30px;"><code>emerge -C =libpng-1.2*</code></p>
<p style="padding-left:60px;"><code> </code></p>
<p style="padding-left:30px;"><code>rm -f /usr/lib/libpng12.so*</code></p>
<p style="padding-left:30px;"><code>emerge -1 =libpng-1.4*</code></p>
<p><code> </code></p>
<p style="padding-left:30px;"><code>revdep-rebuild -- --keep-going</code></p>
<p>Se il tutto (dopo aver fatto i passaggi sopra scritti) non dovesse funzionare provare con:</p>
<p style="padding-left:30px;"><code>lafilefixer --justfixit</code></p>

<p>Morale della favola? Oh ve ne sono parecchi:</p>
<ol>
<li><strong><span style="text-decoration:underline;">MAI</span><span style="font-weight:normal;"> aggiornare Gentoo la sera o quando si è stanchi perchè, se chiudete il terminale senza rendervi conto che c&#8217;è scritto qualcosa, poi fate questa fine xD</span></strong></li>
<li><strong><span style="font-weight:normal;">prima di dare revdep-rebuild controllate di avere installato <em>lafilefixer</em> o dovrete rifare tutto per la </span>terza</strong> volta!</li>
<li>ricordarsi che libpng12 serve per chromium-bin (solo se usate il BIN) quindi dovrete reinstallare libpng-1.2.44 in un nuovo slot <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </li>

<p>Ovviamente questa cosa mi ha richiesto un po&#8217; di tempo (sia per configurarlo ad hoc ma soprattutto per compilare)&#8230;</p>
<ul>
<li>32 minuti circa per il kernel</li>
<li>xorg-server circa 5 ore e 30 minuti</li>
<li>gnome circa 6 ore e 50 minuti</li>
</ul>
<p>La cosa che mi ha sorpreso (a parte il tempo) è stato che il mio povero eeepc non si èassolutamente scaldato&#8230;pensavo di dover andar li con l&#8217;estintore e invece fino alla fine si è comportato veramente bene, un po&#8217; tiepido ma niente di che!</p>

<p>Bene, <a href="http://samba.anu.edu.au/rsync/" target="_blank">Rsync</a> è quello che fa per voi!</p>
<p>Gli usi di questo potentissimo tool sono molti, io ve ne insegnerò un che mi è tornato utile ultimamente:</p>
<p style="padding-left:30px;"><code>﻿rsync -auv --stats  /PERCORSO-SORGENTE/  /PERCORSO-DESTINAZIONE/</code></p>
<p>Con questo comando praticamente avrete i medesimi file in entrambe le cartelle e, se vi sono già file uguali, li salta. Praticamente è un backup incrementale <img src='http://s2.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>Mi raccomando di <strong>mettere sempre la / alla fine </strong>altrimenti succederà questo:</p>
<p>Se <strong>metto la / alla fine</strong> allora avrò questa situazione:</p>
<p style="padding-left:30px;">SORGENTE:<br />
Cartella A \<br />
File1<br />
File2<br />
File3<br />
DESTINAZIONE:<br />
Cartella A \<br />

Altrimenti se <strong>NON metto la / alla fine </strong>avrò quest&#8217;altra situazione:</p>

<p style="padding-left:30px;"><code>mkdir /usr/local/portage</code></p>
<p>Ora editiamo make.conf e aggiungiamo tale riga:</p>
<p style="padding-left:30px;"><code>PORTDIR_OVERLAY="/usr/local/portage"</code></p>
<p>Chiudiamo l&#8217;editor e cerchiamo la categoria e il nomepacchetto del pacchetto che ci interessa con:</p>
<p style="padding-left:30px;"><code>emerge -s <em>$nomepacchetto</em></code></p>
<p>Creiamo la cartella <em>$categoria/$nomepacchetto</em> (in questo caso gnome-base/gnome):</p>
<p style="padding-left:30px;"><code>mkdir -p /usr/local/portage/gnome-base/gnome</code></p>
<p>Copiamo l&#8217;ebuild ufficiale nella cartella appena creata:</p>
<p style="padding-left:30px;"><code>cp /usr/portage/gnome-base/gnome/gnome-2.26.3.ebuild /usr/local/portage/gnome-base/gnome/gnome-2.26.3.ebuild</code></p>
<p>Entriamo nella cartella:</p>
<p style="padding-left:30px;"><code>cd /usr/local/portage/gnome-base/gnome/</code></p>
<p>Editiamo il nostro ebuild in tranquillità togliendo i softwares che non ci interessano:</p>
<p style="padding-left:30px;"><code>nano -w gnome-2.26.3.ebuild</code></p>
<p>Chiudiamo l&#8217;editor e generiamo il file manifest (<span style="text-decoration:underline;"><strong>da fare ogni volta che si edita l&#8217;ebuild!</strong></span>)</p>
<p style="padding-left:30px;"><code>ebuild gnome-2.26.3.ebuild manifest</code></p>
<p>Disinstalliamo ora i pacchetti che non ci interessano con:</p>
<p style="padding-left:30px;"><code>emerge -C <em>$nomepacchetti</em></code></p>
<p>Ora potete dare:</p>
<p style="padding-left:30px;"><code>emerge -uDavN world</code></p>
