## ==========================
|
||||||
|
## PARTITIONS / FILESYSTEMS:
|
||||||
|
## ==========================
|
||||||
|
|
||||||
|
## define your partitions and filesystems like this:
|
||||||
|
##
|
||||||
|
## PART <mountpoint/lvm/btrfs.X> <filesystem/VG> <size in MB>
|
||||||
|
##
|
||||||
|
## * <mountpoint/lvm/btrfs.X>
|
||||||
|
## mountpoint for this filesystem *OR*
|
||||||
|
## keyword 'lvm' to use this PART as volume group (VG) for LVM *OR*
|
||||||
|
## identifier 'btrfs.X' to use this PART as volume for
|
||||||
|
## btrfs subvolumes. X can be replaced with a unique
|
||||||
|
## alphanumeric keyword
|
||||||
|
## NOTE: no support btrfs multi-device volumes
|
||||||
|
## NOTE: reiserfs support is deprecated and will be removed in a future version
|
||||||
|
## * <filesystem/VG>
|
||||||
|
## can be ext2, ext3, ext4, btrfs, reiserfs, xfs, swap *OR* name
|
||||||
|
## of the LVM volume group (VG), if this PART is a VG.
|
||||||
|
## * <size>
|
||||||
|
## you can use the keyword 'all' to assign all the
|
||||||
|
## remaining space of the drive to the *last* partition.
|
||||||
|
## you can use M/G/T for unit specification in MiB/GiB/TiB
|
||||||
|
##
|
||||||
|
## notes:
|
||||||
|
## - extended partitions are created automatically
|
||||||
|
## - '/boot' cannot be on a xfs filesystem
|
||||||
|
## - '/boot' cannot be on LVM!
|
||||||
|
## - when using software RAID 0, you need a '/boot' partition
|
||||||
|
##
|
||||||
|
## example without LVM (default):
|
||||||
|
## -> 4GB swapspace
|
||||||
|
## -> 1024MB /boot
|
||||||
|
## -> 10GB /
|
||||||
|
## -> 5GB /tmp
|
||||||
|
## -> all the rest to /home
|
||||||
|
#PART swap swap 4G
|
||||||
|
#PART /boot ext2 1024M
|
||||||
|
#PART / ext4 10G
|
||||||
|
#PART /tmp xfs 5G
|
||||||
|
#PART /home ext3 all
|
||||||
|
#
|
||||||
|
##
|
||||||
|
## to activate LVM, you have to define volume groups and logical volumes
|
||||||
|
##
|
||||||
|
## example with LVM:
|
||||||
|
#
|
||||||
|
## normal filesystems and volume group definitions:
|
||||||
|
## -> 1024MB boot (not on lvm)
|
||||||
|
## -> all the rest for LVM VG 'vg0'
|
||||||
|
#PART /boot ext3 1024M
|
||||||
|
#PART lvm vg0 all
|
||||||
|
#
|
||||||
|
## logical volume definitions:
|
||||||
|
#LV <VG> <name> <mount> <filesystem> <size>
|
||||||
|
#
|
||||||
|
#LV vg0 root / ext4 10G
|
||||||
|
#LV vg0 swap swap swap 4G
|
||||||
|
#LV vg0 home /home xfs 20G
|
||||||
|
#
|
||||||
|
##
|
||||||
|
## to use btrfs subvolumes, define a volume identifier on a partition
|
||||||
|
##
|
||||||
|
## example with btrfs subvolumes:
|
||||||
|
##
|
||||||
|
## -> all space on one partition with volume 'btrfs.1'
|
||||||
|
#PART btrfs.1 btrfs all
|
||||||
|
##
|
||||||
|
## btrfs subvolume definitions:
|
||||||
|
#SUBVOL <volume> <subvolume> <mount>
|
||||||
|
#
|
||||||
|
#SUBVOL btrfs.1 @ /
|
||||||
|
#SUBVOL btrfs.1 @/usr /usr
|
||||||
|
#SUBVOL btrfs.1 @home /home
|
||||||
|
#
|
||||||
|
## your system has the following devices:
|
||||||
|
#
|
||||||
|
# Disk /dev/nvme0n1: 1.93 TB (=> 1.75 TiB)
|
||||||
|
# Disk /dev/nvme1n1: 1.93 TB (=> 1.75 TiB)
|
||||||
|
#
|
||||||
|
## Based on your disks and which RAID level you will choose you have
|
||||||
|
## the following free space to allocate (in GiB):
|
||||||
|
# RAID 0: ~3576
|
||||||
|
# RAID 1: ~1788
|
||||||
|
#
|
||||||
|
|
||||||
|
PART swap swap 4G
|
||||||
|
PART /boot ext3 1024M
|
||||||
|
PART / ext4 all

## full path to the operating system image
|

## supported image sources: local dir, ftp, http, nfs
|

## supported image types: tar, tar.gz, tar.bz, tar.bz2, tar.xz, tgz, tbz, txz
