Hey,

I cannot install gentoo, since our internet access is wpa2 encrypted and since wpa_supplicant isnt part of the minimal installation medium.
The multilib-liveCd seems to simply put me in a live environment without a chance on installing it permanently.
Am i getting sth. wrong or am i screwed?

Thanks in advance

Lithokteinos ... it's gentoo based, and so is indistinguishable from the other gentoo provided install media. That said, any boot disk will do, as long as it provides networking it can function as an install medium.

Lithokteinos,

You can try something like:

# ifconfig -a
# ip link set wlan0 up
# wpa_supplicant -B -i wlan0 -c <(wpa_passphrase "ssid" "psk")
# dhcpcd wlan0

Lithokteinos,

None of the code from the boot CD/USB goes into your final install. Its just a toolkit to allow you to install.
Use any toolkit you have to hand.
The only constraint is that you must boot a 64 bit kernel to perform a 64 bit install.

I'm sorry to be pedantic, but isn't there also a limitation in which you also need to boot in U.E.F.I. mode to perform that kind of installation, as well (to install the bootloader or use efibootmgr to add the boot entry)?

keet ... there is, but as the question was on wireless networking specifically, and no mention has been made of efi so far, the assumption would be that its not a requirement for the OP. None the less, sysresccd does support efi booting, and in fact, you can often work around the issue by using {ESP}/efi/boot/bootia64.efi (which many/some efi firmwares support as the default/fallback location for the efi executable) and so the absence of efivars, and efibootmgr, isn't always a showstopper.
