Tips & Tricks
Download the correct ISO for your hardware
The livedvd-x86-x86_64 ISO will work on 32-bit x86 or 64-bit
x86_64. If your architecture is x86, boot with the default. If your arch is
amd64, boot with gentoo64.
The livedvd-amd64 ISO is only for x86_64. Boot with the default.
Code Listing 2.1: How do I become root?
$ sudo su -
You can use passwd to change the password for the user you are logged
into. As root, you can change any user password by issuing the command
passwd username For extra options and setting, please man passwd.
Can I copy the image to a usb stick?
Yes. To determine your device before you plug it in, open a terminal and read
Code Listing 2.2: Determine Device
# tail -f /var/log/messages
You will need at least a 4GB device!
Code Listing 2.3: Copy the image
# dd if=image.iso of=/dev/sdb
Do not point to a partition number!
Not all BIOS support booting from USB devices. Consult your motherboard
Can I resume the autologin?
To resume the KDM autologin, you need to press the ESC key and wait for the
timeout to pass or just hit the enter key to login.
Tips & Tricks
Can I install firmware for my wireless card?
Yes. You just need to copy the firmware to /lib/firmware and reload
your wireless card's kernel modules. The example below installs the firmware for
a Ralink RT2501USB wireless LAN chipset. It requires non-free firmware, which
cannot be included on the Live DVD because of license issues. The firmware is
copied from a 2GB usb stick.
Code Listing 3.1: Install the firmware
# mkdir /mnt/pin
# mount /dev/sdb1 /mnt/pin
# cp /mnt/pin/firmware/rt73.bin /lib/firmware
# modprobe -r rt73usb rt2x00usb rt2x00lib
# modprobe rt73usb
# rc-service wicd restart
How can I set up and enable persistence?
For USB Linux users, a persistent Linux install is one that allows it's user to
save data changes back to the USB storage device instead of leaving the
information in system RAM. This data can then be recovered and used again on
subsequent boots, even when booting from different machines.
Booting with the 'persistence' boot option will allow you to retain your $HOME
changes on a separate removable device or if you have space left on the usb
that the image is booting from, you can then create a partition on there then:
Note: In my testing I ran out of space on a 4GB stick. I ended up using two 4GB
sticks, one for the image and one for persistence. I booted with the option
"persistence persistence_mb=2G", and all was well.
- Create a FS (extfs,reiserfs,xfs etc..)
- Create an empty file named 'persistence-mode'
This partition will be used to create a loopback image that will allow
persistent data on reboots.
There is an optional boot parameter which can set the image size you wish for
$HOME which is persistence_mb=300 for example, will make a 300M size image for
your persistent data. The minimum requirement is 256M for now which is the
