installation. This option is mostly for developers and not meant for
general use.
+Rescue Boot::
+
+This option allows you to boot an existing installation. It searches
+all attached hard disks, and if it finds an existing installation,
+boots directly into that disk using the existing Linux kernel. This
+can be useful if there are problems with the boot block (grub), or the
+BIOS is unable to read the boot block from the disk.
+
Test Memory::
Runs 'memtest86+'. This is useful to check if your memory if
functional and error free.
-You normally select *Install Proxmox VE* to start the installation.

After that you get prompted to select the target hard disk(s). The
`Options` button aside lets you select the target file system, and
defaults to `ext4`. The installer uses LVM if you select 'ext3',
'ext4' or 'xfs' as file system, and offers additional option to
-restrict LVM space.

+If you have more than one disk, you can also use ZFS as file system.
+ZFS supports several software RAID levels, so this is specially useful
+if you do not have a hardware RAID controller. The `Options` button
+lets you select the ZFS RAID level, and you can choose disks there.

+zone and keyboard layout. You also need to specify your email address
+and select a superuser password.
+
+The last step is the network configuration. Please note that you can
+use either IPv4 or IPv6 here, but not both. If you want to configure a
+dual stack node, you can easily do that after installation.
+
+If you press `Next` now, installation starts to format disks, and
+copies packages to the target. Please wait until that is finished,
+then reboot the server.

The installer creates a Volume Group (VG) called `pve`, and additional
Logical Volumes (LVs) called `root`, `data` and `swap`. The size of
those volumes can be controlled with:
To define the amount of free space left in LVM volume group `pve`.
16GB is the default if storage available > 128GB, `hdsize/8` otherwise.

+ZFS Performance Tips
+^^^^^^^^^^^^^^^^^^^^
+
ZFS uses a lot of memory, so it is best to add additional 8-16GB RAM
if you want to use ZFS.
-.Use fast SSD as write cache
-
-ZFS provides the feature to use a fast SSD drive as write cache. The
+ZFS also provides the feature to use a fast SSD drive as write cache. The
write cache is called the ZFS Intent Log (ZIL). You can add that after
installation using the following command:
zpool add <pool-name> log </dev/path_to_fast_ssd>

+System Software Updates
+-----------------------
-If you press `Next` now, installation starts to format disks, and
-copies packages to the target. Please wait until that is finished,
-then reboot the server.
+We provide regular package updates on all repositories. You can
+install those update using the GUI, or you can directly run the CLI
+command 'apt-get':

+ apt-get update
+ apt-get dist-upgrade
+
+NOTE: The 'apt' package management system is extremely flexible and
+provides countless of feature - see `man apt-get` or <<Hertzog13>> for
+additional information.
+
+You should do such updates at regular intervals, or when we release
+versions with security related fixes. Major system upgrades are
+announced at the https://forum.proxmox.com/[Forum]. Those announcement
+also contain detailed upgrade instructions.
+
+TIP: We recommend to run regular upgrades, because it is important to
+get the latest security updates.
