 |
|
Hello gentoomen, I am transitioning from Arch to Gentoo on my new rig and with the combination of systemd + LUKS/LVM, and being my first time, I knew this would get confusing so I spent some time trying to plan it out.
Now I ask of you to peer review it and help me ascend on my glorious journey, any suggestions or recommendations are welcome. Thank you.

This is for: UEFI, Ethernet, Luks on LVM, and systemd.
Hardware:
- Intel i7-6700k
- Nvidia GTX 980TI
- 16Gb RAM
- Samsung 500Gb SSD
- Western Digital 2Tb HDD
___________________________________________________________________________
Here is my game plan:

Mount Graph: http://i.imgur.com/8g2vF6W.png
*Slightly different from pics (eg. /boot/efi)
- Encrypted LVM vgs w/ keyfiles
- SSH (or VNC)
- Decrease boot time
- Mail Server
- Gaming Rig
- Bitcoin mining
- WM ricing
___________________________________________________________________________
Parts that I know are wrong and I need guidance for:
- saving keyfiles
- Installing systemd instead of OpenRC.
Edit: After adding in the systemd componenets I am 100% uncomfortable with how this is set as it feels mangled.

Check Connection:
| Code: | | # ping -c 3 gentoo.com |
Check UEFI:
| Code: | | # ls /sys/firmware/efi/efivars |
Partitioning:
| Code: | # parted /dev/sda
# (parted) mklabel gpt
# (parted) mkpart ESP fat32 1MiB 513MiB
# (parted) set 1 boot on
# (parted) mkpart primary ext4 513MiB 100%
# parted /dev/sdb
# (parted) mkpart primary ext4 1MiB 100% |

// Not sure at what point /tmp should come in and be formatted as /tmpfs |
Mount:
| Code: | # mount /dev/mapper/root /mnt/gentoo
# mkdir -p /mnt/gentoo/boot; mount /dev/sda1 /mnt/gentoo/boot
# mkdir -p /mnt/gentoo/usr; mount /dev/mapper/usr /mnt/gentoo/usr

# mount /dev/mapper/virtualmachines /mnt/gentoo/home/artificial/VMs
# mount /dev/mapper/games /mnt/gentoo/home/artificial/Games |
Setting time and date:
Downloading the stage tarball:
| Code: | # cd /mnt/gentoo
# links https://www.gentoo.org/downloads/mirrors/
// ‘D’ to download tarball, ‘Q’ to quit |
Unpacking the stage tarball:
| Code: | | # tar xvjpf stage3*.tar.bz2 -xattrs |
Configure compile options:
| Code: |
# nano -w /mnt/gentoo/etc/portage/make.conf
> CFLAGS=”-march=native -O2 -pipe”
> CXXFLAGS=”${CFLAGS}”
> MAKEOPTS="-j9"
> VIDEO_CARDS="intel nvidia" |
Selecting mirrors:
| Code: | # mirrorselect -i -o >> /mnt/gentoo/etc/portage/make.conf
# mkdir /mnt/gentoo/etc/portage/repos.conf
# cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf
# cat /mnt/gentoo/etc/portage/repos.conf/gentoo.conf
> [gentoo]
> location = /usr/portage
> sync-type = rsync
> sync-uri = rsync://rsync.gentoo.org/gentoo-portage
> auto-sync = yes |
Copy DNS info:
| Code: |
# cp -L /etc/resolv.conf /mnt/gentoo/etc |
Mounting the necessary filesystems:
| Code: |
# mount -t 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
|
Entering the new environment:
| Code: |
# chroot /mnt/gentoo /bin/bash
# source /etc/profile
# export PS1=”(chroot) $PS1” |
Installing a portage snapshot:
| Code: | # emerge-webrsync
# emerge --sync |
Reading news items:
| Code: |
# eselect news list
# eselect news read
# eselect news purge |
Choosing the right profile:
| Code: | # eselect profile list
# eselect profile set <insert # here>
// At this point it tells me to look at the systemd page, but its not a continuation of this guide so it confuses me somewhat. |
Time:
| Code: | # echo “America/Los_Angeles” > /etc/timezone
# emerge --config sys-libs/timezone-data |
Locale:
| Code: | # nano -w /etc/locale.gen
# locale-gen
# locale -a
# eselect locale list
# eselect locale set <insert # here>
# env-update && source /etc/profile && export PS1=”(chroot) $PS1” |
Installing the sources:
| Code: | # emerge --ask sys-kernel/gentoo-sources
# ls -l /usr/src/linux
// I decided against the hardened kernel as it causes too many problems with Steam. |
Intro to manual kernal configuration:
| Code: |
# emerge --ask sys-apps/pciutils
# cd /usr/src/linux
# make menuconfig |
Required options:

# genkernel --install all
# genkernel --udev --lvm --luks --disklabel initramfs
**// systemd page says 'genkernel --install all', but is that necessary?**
|
Configuring the modules:
| Code: | // Replace <kernel version> w/ version.
# find /lib/modules/<kernel version>/ -type f -iname ‘*.o’ -or -iname ‘*.ko’ | less

Activating lvm
| Code: | | # systemctl enable lvm2-monitor.service |
___________________________________________________________________________
Edit: Added tmp to fstab, added systemd kernel config, changed initramfs, added LVM daemon, added systemd to GRUB2 config, added root & user passwd, added hostnamectl commands, added systemd installation, added systemd-networkd, removed /tmp as systemd automatically sets it, added Activating lvm, added updated systemd requirements, added VIDEO_CARDS variable to make.conf, removed init & boot configuration, system logger, and cron daemon section, switched networking and hostname commands for systemd counterparts. |
