# instalando rewrite module no apache
sudo a2enmod rewrite
sudo /etc/init.d/apache2 force-reload
/* Basically, to get mod_rewrite to work, load the module by symlinking to mods-available/rewrite.conf in mods-enabled, then set AllowOverride to “all” in sites-available/default in both the root (”/”) container and the /var/www/ container. Whilst you’re there, it may be a good idea to get rid of the RedirectMatch, simply because it’s annoying… I haven’t, but only because I haven’t bothered to put something in the root of the default site. */

# copiar partições
<iceroot> sudo dd if=/dev/sdX of=/dev/sdX
<iceroot> afeijo: maybe you have to edit the uuid in /etc/fstab on the new drive. you can get the new uuid with "sudo blkid /dev/sdb"
<iceroot> afeijo: but this should fix it "sudo dd if=/dev/sdb of=/dev/sda1 bs=512 count=1" when sda is the new drive. then you have the partion-layout + mbr there
