Gentoo Samsung Cronos ​

This is a setup with the intent of having a Dual boot install from Arch Linux It might be helpful if so is not the case for you but you have this laptop or a similar one. This has been tested on a **Samsung NP700Z3A**

Start here ​

Stage tarball ​

sh
tar xpvf stage3-amd64-20190131T214503Z.tar.xz --xattrs-include='*.*' --numeric-owner

CFLAGS look up Sandy Bridge ​

Gentoo wiki Safe CLAGS

sh
# /etc/portage/make.conf
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=sandybridge -O2 -pipe"
CXXFLAGS="${CFLAGS}"

Installing base system ​

MAKEOPTS="-j2"

Follow the wiki slavic: ​

sh
mkdir --parents /mnt/gentoo/etc/portage/repos.conf
cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf

cp --dereference /etc/resolv.conf /mnt/gentoo/etc/

mount --types proc /proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/dev

When using non-Gentoo installation media, this might not be sufficient. Some distributions make /dev/shm a symbolic link to /run/shm/ which, after the chroot, becomes invalid. Making /dev/shm/ a proper tmpfs mount up front can fix this:

sh
test -L /dev/shm && rm /dev/shm && mkdir /dev/shm
mount --types tmpfs --options nosuid,nodev,noexec shm /dev/shm
# Also ensure that mode 1777 is set:

chmod 1777 /dev/shm

chroot ​

sh
chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) ${PS1}"
