d-i user-setup/encrypt-home boolean false 

The passwd/root-password-crypted and passwd/user-password-crypted variables can also be preseeded with “!” as their value. In that case, the corresponding account is disabled. This may be convenient for the root account, provided of course that an alternative method is set up to allow administrative activities or root login (for instance by using SSH key authentication or sudo ). 

The following command (available from the whois package) can be used to generate a SHA-512 based crypt(3) hash for a password: 

mkpasswd -m sha-512 

## B.4.6. Clock and time zone setup 

# Controls whether or not the hardware clock is set to UTC. d-i clock-setup/utc boolean true 

# You may set this to any valid setting for $TZ; see the contents of # /usr/share/zoneinfo/ for valid values. d-i time/zone string US/Eastern 

# Controls whether to use NTP to set the clock during the install d-i clock-setup/ntp boolean true # NTP server to use. The default is almost always fine here. #d-i clock-setup/ntp-server string ntp.example.com 

## B.4.7. 64-bit ARM specific disk storage 

The arm64 offers two unique kinds of disk storage - DASD and FCP (or zFCP). 

# Activate DASD disks #d-i s390-dasd/dasd string 0.0.0200,0.0.0300,0.0.0400 

# DASD configuration; by default dasdfmt (low-level format) if needed #d-i s390-dasd/auto-format boolean true #d-i s390-dasd/force-format boolean true 

# zFCP activation and configuration # d-i s390-zfcp/zfcp string 0.0.1b34:0x400870075678a1b2:0x201480c800000000, \ # 0.0.1b34:0x400870075679a1b2:0x201480c800000000 

## B.4.8. Partitioning 

Using preseeding to partition the harddisk is limited to what is supported by partman-auto . You can choose to partition either existing free space on a disk or a whole disk. The layout of the disk can be determined by using a predefined recipe, a custom recipe from a recipe file or a recipe included in the preconfiguration file.
