User:Pnoecker/standard install

This howto describes how to setup a generic LVM2 install. It is a standalone installation walk through, loosely based on the official installations finished product.

Warning

You may try this installation method at your own risk! Please note: this guide is outside of the official installation documentation, and cannot be supported. If you choose to use this, we assume you know what you are doing and you are on your own!

Prepare the hard drive, and partitions

Before you begin, make sure you are partitioning the correct drive. For the rest of this tutorial, we will be using /dev/sdX as a placeholder.

root # lsblk
#NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
#sda             8:0    0  1.8T  0 disk 
#├─sdX1          8:1    0    1M  0 bios_boot
#├─sdX2          8:2    0    8G  0 esp      /efi
#└─sdX3          8:3    0  1.8T  0 part 
#  ├─main-boot 254:0    0  500G  0 lvm  /boot
#  ├─main-swap 254:0    0  500G  0 lvm  [swap]
#  ├─main-root 254:0    0  500G  0 lvm  /

link your drive to /dev/sdX

to make following this guide easier you can set udev rules and link the drive you're installing to /dev/sdX so everything is copy paste. just replace the kernel's == sda/mmc/nvme to match your target drive.

hda/sda drives:

root # echo 'KERNEL=="sda*", SYMLINK+="sdX%n"' > /etc/udev/rules.d/01-funtoo.rules
root # udevadm control --reload-rules
root # udevadm trigger

mmc/nvme drives:

root # echo 'KERNEL=="mmcblk0", SYMLINK+="sdX"' > /etc/udev/rules.d/01-funtoo.rules
root # echo 'KERNEL=="mmcblk0p*", SYMLINK+="sdX%n"' >> /etc/udev/rules.d/01-funtoo.rules
root # udevadm control --reload-rules
root # udevadm trigger

verify linking

root # ls -al /dev/sdX*
lrwxrwxrwx 1 root root 3 Jul 31 14:00 /dev/sdX -> sde
lrwxrwxrwx 1 root root 4 Jul 31 14:00 /dev/sdX1 -> sde1
lrwxrwxrwx 1 root root 4 Jul 31 14:00 /dev/sdX2 -> sde2

Partition

UEFI Partitioning

root # gdisk /dev/sdX

Within gdisk, follow these steps:

Empty the partition table:

Command: o ↵
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y ↵

Create bios boot partition:

Command: n ↵
Partition Number: 1 ↵
First sector: ↵
Last sector: +1M ↵
Hex Code: EF02 ↵

Create efi esp partition:

Command: n ↵
Partition Number: 2 ↵
First sector: ↵
Last sector: +64M ↵
Hex Code: EF00 ↵

Create partition which will be our LVM2 virtual partition:

Command: n ↵
Partition Number: 3 ↵
First sector: ↵
Last sector: ↵ (for rest of disk)
Hex Code: ↵

Write Partition Table To Disk:

Command: w ↵
Do you want to proceed? (Y/N): Y ↵

The partition table will now be written to the disk and gdisk will close.

Create and mount filesystems.

Create esp filesystem

root # mkfs.vfat -F 32 /dev/sdX2

label esp system for fstab later on:

root # fatlabel /dev/sdX2 "EFI"

Create LVM2 volume

Create LVM volume for /, /boot, and swap

root # pvcreate /dev/sdX3

root # vgcreate vg /dev/sdX3

root # lvcreate -L256M --name boot vg

Note

Replace "2G" with the amount of swap you would like to make available.

root # lvcreate -L2G --name swap vg

root # lvcreate -l 100%FREE --name root vg

Note

The "-l 100%FREE" option above will use the remainder of the disk for your root partition. If you would prefer to create separate for /home or /var (for example), you can instead continue to use the "-LXXG" option for fixed sizes.

Create filesystems on LVM volumes

swap:

root # mkswap /dev/mapper/vg-swap

for ext4:

root # mkfs.ext4 /dev/mapper/vg-boot

root # mkfs.ext4 /dev/mapper/vg-root

for xfs:

root # mkfs.xfs /dev/mapper/vg-boot

root # mkfs.xfs /dev/mapper/vg-root

Create directories for chroot

root # mkdir -p /mnt/funtoo

Mount filesystems

root # mount /dev/mapper/vg-root /mnt/funtoo

root # mkdir /mnt/funtoo/boot

root # mount /dev/mapper/vg-boot /mnt/funtoo/boot

Set the date

Note

See the official Funtoo docs on setting the date.

Install the Funtoo starge tarball of your choice

Note

These instructions will be using the generic64 next minimal stage3. You should adjust them accordingly.

Generic_64

or a stage more closely aligned to your hardware:

Subarches

or funtoo from scratch generated stages:

FFS BRUH

root # cd /mnt/funtoo

root # wget https://build.funtoo.org/next/x86-64bit/generic_64/2022-09-13/stage3-generic_64-next-2022-09-13.tar.xz

root # tar --numeric-owner --xattrs --xattrs-include='*' -xpf *stage3*.tar.xz && rm -f *stage3*.tar.xz

Chroot into your new system

Traditional Method

root # mkdir /mnt/funtoo/proc

root # mount -t proc none /mnt/funtoo/proc

root # mkdir /mnt/funtoo/dev

root # mount --rbind /dev /mnt/funtoo/dev

root # mkdir /mnt/funtoo/sys

root # mount --rbind /sys /mnt/funtoo/sys

root # env -i HOME=/root TERM=$TERM $(which chroot) /mnt/funtoo /bin/bash -l

Fchroot Method

root # fchroot .

Configure your system

Set a new root password

root # passwd

Set hostname

root # echo 'hostname="NewFuntooInstall"' > /etc/conf.d/hostname

Set up DNS resolution

Note

We are using the Cloudflare DNS server address here. Feel free to use your own.

root # echo "nameserver 1.1.1.1" > /etc/resolv.conf

Set your timezone

root # ln -sf /usr/share/zoneinfo/$(tzselect) /etc/localtime

Note your filesystem information

root # blkid

/dev/sdX2: UUID="6453-0C55" TYPE="vfat" PARTLABEL="efi" PARTUUID="4e195c4b-f88c-4205-b9df-79a879704b2f"

/dev/mapper/vg-root: UUID="2eaf45e6-d33b-4155-b4ca-63a2fdbfb896" TYPE="ext4"

Configure /etc/fstab

Note

this example uses xfs

root # cat > /etc/fstab << 'EOF'
UUID=hvz79n-I2VE-nR1c-0hDQ-PVkR-3GRb-rnuJ9C /boot xfs noauto,noatime,nodiratime,defaults 0 1
UUID=a9188bc3-7def-422b-990d-9de431825779 none swap sw 0 0
UUID=2eaf45e6-d33b-4155-b4ca-63a2fdbfb896 / xfs noatime,nodiratime,defaults 0 1
tmpfs /var/tmp/portage tmpfs uid=portage,gid=portage,mode=775,noatime 0 0
LABEL=EFI /boot/efi vfat umask=0077 0 1
EOF

Note

run nano /etc/fstab & change the uuid values to your particular system

compile in ram:

root # mkdir /var/tmp/portage
root # chown portage:portage /var/tmp/portage
root # mount /var/tmp/portage

or exclude compiling in ram if your machine's not powerful enough:

root # umount /var/tmp/portage

Portage

Download the portage tree

root # ego sync

Edit package USE-flags

root # cat > /etc/portage/package.use <<'EOF'
*/* device-mapper lvm
sys-kernel/linux-firmware initramfs
EOF

Install necessary packages

root # emerge grub haveged intel-microcode linux-firmware lvm2 iucode_tool shim mokutil

Configure services to start at boot

root # rc-update add device-mapper sysinit

root # rc-update add lvmetad sysinit

root # rc-update add haveged default

root # rc-update add busybox-ntpd default

Install a bootloader

Configure /etc/boot.conf

Note

The UUID parameter is set to the UUID of /dev/sdX3 as found from the blkid command above.

root # cat > /etc/boot.conf <<'EOF'
boot {
    generate grub
    default "Funtoo Linux"
    timeout 3
}
"Funtoo Linux" {
    kernel kernel[-v]
    initrd initramfs[-v]
    params += ramdisk.activate=lvm real_root=auto rootfstype=auto resume=/dev/mapper/vg-swap quiet
}
EOF

Install GRUB

For BIOS systems & UEFI legacy mode support

root # grub-install --target=i386-pc --no-floppy /dev/sdX

For UEFI systems

root # mount -o remount,rw /sys/firmware/efi/efivars

Install grub & shim

load efi directory:

root # mkdir /boot/efi
root # mount /boot/efi

generate a sbat file to install with grub:

root # cat > /usr/share/grub/sbat.csv << EOF
sbat,1,SBAT Version,sbat,1,https://github.com/rhboot/shim/blob/main/SBAT.md
grub,1,Free Software Foundation,grub,2.06,https://www.gnu.org/software/grub/
EOF

64bit systems

root # grub-install --target=x86_64-efi --sbat /usr/share/grub/sbat.csv --efi-directory=/boot/efi --bootloader-id="Funtoo" --recheck /dev/sdX

root # cp /usr/share/shim/BOOTX64.EFI /usr/share/shim/mmx64.efi /boot/efi/EFI/Funtoo

For usb keys & removable drives:

root # grub-install --target=x86_64-efi --sbat /usr/share/grub/sbat.csv --efi-directory=/boot/efi --bootloader-id="BOOT" --no-nvram --recheck /dev/sdX

root # cp /usr/share/shim/BOOTX64.EFI /usr/share/shim/mmx64.efi /boot/efi/EFI/BOOT

root # grub-install --target=i386-efi --sbat /usr/share/grub/sbat.csv --efi-directory=/boot/efi --bootloader-id="Funtoo" --recheck /dev/sdX

root # cp /usr/share/shim/BOOTIA32.EFI /usr/share/shim/mmia32.efi /boot/efi/EFI/Funtoo

For usb keys & removable drives:

root # grub-install --target=i386-efi --sbat /usr/share/grub/sbat.csv --efi-directory=/boot/efi --bootloader-id="BOOT" --no-nvram --recheck /dev/sdX

root # cp /usr/share/shim/BOOTIA32.EFI /usr/share/shim/mmia32.efi /boot/efi/EFI/BOOT

Generate Grub menu

Generate a new initramfs

root # cd /boot && ramdisk --force --plugins=core,lvm $(ls /boot/initramfs-*)

Generate boot menu

root # ego boot update

Finishing installation

From this point, you should be able to finish following the official Funtoo Linux install instructions

Rechroot

In the event of build failure, to rechroot requires unlocking the root, re-mounting, and re-chroot.

root # mount /dev/mapper/vg-root /mnt/funtoo && mount /dev/mapper/vg-boot /mnt/funtoo/boot
root # cd /mnt/funtoo
root # fchroot .
