download sabayon here
for this tutorial i used the following line [64bit version/german mirror] :
wget http://sabayonlinux.cybermirror.org/iso/Sabayon_Linux_5.4_amd64_K.iso
md5 checksum
wget http://sabayonlinux.cybermirror.org/iso/Sabayon_Linux_5.4_amd64_K.iso.md5
pkglist
wget http://sabayonlinux.cybermirror.org/iso/Sabayon_Linux_5.4_amd64_K.iso.pkglist
and to check the md5sum of our iso, we do
md5sum -c ./Sabayon_Linux_5.4_amd64_K.iso.md5
which should output
Sabayon_Linux_5.4_amd64_K.iso: OK
to install via USB stick, without burning a CD we will need to download unetbootin
wget http://downloads.sourceforge.net/project/unetbootin/UNetbootin/494/unetbootin-linux-494?r=http%3A%2F%2Funetbootin.sourceforge.net%2F&ts=1287034974&use_mirror=netcologne
live install
copy the image to a usb using unetbootin,
1. Plug in your USB Drive (Minimum USB Drive capacity 2 GB)
2. Format the USB drive to FAT32
3. Download Unetbootin from http://unetbootin.sourceforge.net/
wget http://downloads.sourceforge.net/project/unetbootin/UNetbootin/494/unetbootin-linux-494?r=http%3A%2F%2Funetbootin.sourceforge.net%2F&ts=1287034974&use_mirror=netcologne
4. Start Unetbootin and select diskimage (use Sabayon_Linux_5.4_amd64_K.iso in this case)
5. Select your USB drive and click “OK” for creating a bootable Sabayon USB drive
6. Reboot with your USB stick, then we can start instaling Sabayon on your PC
it is VERY IMPORTANT, that we write “good” random data on our disk, that we want to encrypt,
to make it a save and good basis for encryption.
to cleanup your harddrive, and overwrite the data with a nice & useful random pattern you can make
dd if=/dev/urandom of=/dev/sdc
if you want to check for bad blocks while writing you can use badblocks. the badblocks command will check your disk for bad blocks while writing random data. the pseudorandom algorithm used by this command is faster (although “less random”) than /dev/urandom, so it can be useful for large disks.
badblocks -s -w -t random -v /dev/sdc
or you can use wipe to be really sure
wipe /dev/sdc
now our usb drive should be clean …
