#. Kernel variant
|
|
|
|
Store the kernel variant in a variable.
|
|
Available variants in official repo are:
|
|
|
|
- linux
|
|
- linux-lts
|
|
- linux-zen
|
|
- linux-hardened
|
|
|
|
::
|
|
|
|
INST_LINVAR='linux'
|
|
|
|
``linux-hardened`` does not support hibernation.
|
|
|
|
#. Unique pool suffix. ZFS expects pool names to be
|
|
unique, therefore it's recommended to create
|
|
pools with a unique suffix::
|
|
|
|
INST_UUID=$(dd if=/dev/urandom bs=1 count=100 2>/dev/null | tr -dc 'a-z0-9' | cut -c-6)
|
|
|
|
#. Identify this installation in ZFS filesystem path::
|
|
|
|
INST_ID=arch
|
|
|
|
#. Target disk
|
|
|
|
List available disks with::
|
|
|
|
ls /dev/disk/by-id/*
|
|
|
|
If using virtio as disk bus, use
|
|
``/dev/disk/by-path/*`` or ``/dev/vd*``.
|
|
|
|
Declare disk array::
|
|
|
|
DISK=(/dev/disk/by-id/ata-FOO /dev/disk/by-id/nvme-BAR)
|
|
|
|
For single disk installation, use::
|
|
|
|
DISK=(/dev/disk/by-id/disk1)
|
|
|
|
#. Choose a primary disk. This disk will be used
|
|
for primary EFI partition and hibernation, default to
|
|
first disk in the array::
|
|
|
|
INST_PRIMARY_DISK=${DISK[0]}
|
|
|
|
If disk path contains colon ``:``, this disk
|
|
can not be used for hibernation. ``encrypt`` mkinitcpio
|
|
hook treats ``:`` as argument separator without a means to
|
|
escape this character.
|
|
|
|
#. Set vdev topology, possible values are:
|
|
|
|
- (not set, single disk or striped; no redundancy)
|
|
- mirror
|
|
- raidz1
|
|
- raidz2
|
|
- raidz3
|
|
|
|
::
|
|
|
|
INST_VDEV=
|
|
|
|
#. Set partition size:
|
|
|
|
Set ESP size. ESP contains Live ISO for recovery,
|
|
as described in `optional configurations <4-optional-configuration.html>`__::
|
|
|
|
INST_PARTSIZE_ESP=4 # in GB
|
|
#INST_PARTSIZE_ESP=1 # if local recovery is not needed
|
|
|
|
Set boot pool size. To avoid running out of space while using
|
|
boot environments, the minimum is 4GB. Adjust the size if you
|
|
intend to use multiple kernel/distros::
|
|
|
|
INST_PARTSIZE_BPOOL=4
|
|
|
|
Set swap size. It's `recommended <https://chrisdown.name/2018/01/02/in-defence-of-swap.html>`__
|
|
to setup a swap partition. If you intend to use hibernation,
|
|
the minimum should be no less than RAM size. Skip if swap is not needed::
|
|
|
|
INST_PARTSIZE_SWAP=8
|
|
|
|
Root pool size, use all remaining disk space if not set::
|
|
|
|
INST_PARTSIZE_RPOOL=
|
