Hello Gentoo community ! I'm new ! 8)

I've used Debian / Crunchbang OS for 6 years and i would like to switch to another Linux Distro. I'm very interested in Gentoo and i've successfully installed it on my laptop last year (from a Stage3), but for some reasons, i've removed it and i've reinstalled Debian.

And now, i'm ready to retry the travel ! 8)

But i don't have an internet access with my laptop (very long story), and i would like to be able to install gentoo from a fully fonctionnal liveUSB.

I've already tried the liveCD but there are some problems (I was unable to mount any usb drive for instance), and it was not possible to install gentoo from the liveCD.

So here is my questions : Is there a way to create a Gentoo LiveUSB, which can be used as a fully fonctionnal Gentoo system (whith persistent data) and as a support for complete offline installation of a new Gentoo fresh system on a computer ?

Greetings,

Gouwi

Gouwi,

Welcome to Gentoo.

The simple answer to you question is No. Gentoo is built from source, not binary packages and by and large the binary packages don't exist. Even if they did, you get somebody elses Gentoo, not yours.

A more complex answer is Maybe. If you fetch the current LiveDVD you can put it onto a USB stick.
You will find instructions for doing a binary install of likewohas Gentoo on the forums. The LiveCD uses aufs to fake some persistent storage, so it will run emerge.

The final answer is yes - you can use Sneakernet which addresses your issue in another way.

Gentoo is about choice ... theres your fist decision point.

I have done networkless gentoo installs in the past, but I've always had one working gentoo box with a network connection to begin with(Not strictly necessary, but helps a lot).

What I did was made a two partition USB, one partition was a mint live image, the other was a storage partition containing a portage snapshot, a stage3, and all the source tarballs I needed corresponding to the portage snapshot.(I also took with me a premade fstab, make.conf, and other files)
Obtaining the correct sources is tricky unless you have a current gentoo installation. If you have one, you simply emerge -ef system <list of packages> and copy over /usr/portage/distfiles, or only the bits you need.
Then, when you're doing the install, once you untar portage and copy over your distfiles into the new environment, you can just chroot in and emerge all your packages. Hopefully when that's done, you can boot, and then access the internet to --sync and -uaNDv world.

Hope this helps.

If you download a stage 3 and a portage snapshot and can boot some sort of linux
you can get a command-line Gentoo from there; then its a question of pulling packages
down using emerge --fetchonly using eg: an internet cafe connection.

At least, that's how I last installed Gentoo. But it's a fair amount to download: my
/usr/portage/distfiles directory is around 6G, basically all the packages I'll ever use.
