#. Create boot pool::

zpool create \
|
|
-o compatibility=grub2 \
|
|
-o ashift=12 \
|
|
-o autotrim=on \
|
|
-O acltype=posixacl \
|
|
-O canmount=off \
|
|
-O compression=lz4 \
|
|
-O devices=off \
|
|
-O normalization=formD \
|
|
-O relatime=on \
|

-O xattr=sa \
|

-O mountpoint=/boot \

|
|
mirror \
|
|
$(for i in ${DISK}; do
|
|
printf "$i-part2 ";
|
|
done)
|
|
|
|
If not using a multi-disk setup, remove ``mirror``.
|
|
|
|
You should not need to customize any of the options for the boot pool.
|
|
|
|
GRUB does not support all of the zpool features. See ``spa_feature_names``
|
|
in `grub-core/fs/zfs/zfs.c
|
|
<http://git.savannah.gnu.org/cgit/grub.git/tree/grub-core/fs/zfs/zfs.c#n276>`__.
|
|
This step creates a separate boot pool for ``/boot`` with the features
|
|
limited to only those that GRUB supports, allowing the root pool to use
|
|
any/all features.
|
|
|
|
Features enabled with ``-o compatibility=grub2`` can be seen
|
|
`here <https://github.com/openzfs/zfs/blob/master/cmd/zpool/compatibility.d/grub2>`__.

#. This section implements dataset layout as described in `overview <1-preparation.html>`__.
|
|
|
|
Create root system container:
|
|
|
|
- Unencrypted::
|
|
|
|
zfs create \
|
|
-o canmount=off \
|
|
-o mountpoint=none \
|
|
rpool/archlinux
|
|
|
|
- Encrypted:
|
|
|
|
Pick a strong password. Once compromised, changing password will not keep your
|
|
data safe. See ``zfs-change-key(8)`` for more info::
|
|
|
|
zfs create \
|
|
-o canmount=off \
|
|
-o mountpoint=none \
|
|
-o encryption=on \
|
|
-o keylocation=prompt \
|
|
-o keyformat=passphrase \
|
|
rpool/archlinux
|
|
|
|
Create system datasets::
|
|
|
|
zfs create -o canmount=on -o mountpoint=/ rpool/archlinux/root
|
|
zfs create -o canmount=on -o mountpoint=/home rpool/archlinux/home
|
|
zfs create -o canmount=off -o mountpoint=/var rpool/archlinux/var
|
|
zfs create -o canmount=on rpool/archlinux/var/lib
|
|
zfs create -o canmount=on rpool/archlinux/var/log
|
|
|
|
Create boot dataset::
|
|
|
|
zfs create -o canmount=off -o mountpoint=none bpool/archlinux
|
|
zfs create -o canmount=on -o mountpoint=/boot bpool/archlinux/root
|
|
|
|
#. Format and mount ESP::
|
|
|
|
for i in ${DISK}; do
|
|
mkfs.vfat -n EFI ${i}-part1
|
|
mkdir -p /mnt/boot/efis/${i##*/}-part1
|
|
mount -t vfat ${i}-part1 /mnt/boot/efis/${i##*/}-part1
|
|
done
|
|
|
|
mkdir -p /mnt/boot/efi
|
|
mount -t vfat $(echo $DISK | cut -f1 -d\ )-part1 /mnt/boot/efi
|
|
|
|
#. Install packages::
|
|
|
|
pacstrap /mnt base vi mandoc grub efibootmgr mkinitcpio
|
|
|
|
CompatibleVer=$(pacman -Si zfs-linux | grep 'Depends On' | sed "s|.*linux=||" | awk '{ print $1 }')
