# Preconfiguration file for jessie.

d-i debian-installer/locale string en_US
### Preseed for Ubuntu 18.04
# Derived from:
### Compatibility
# Tested with the netboot image:
# Might work with the regular image (not tested):
### Authentication
# We recommend to use public key authentication and therefore disabled the root
# password. The script will do all the hard work for you.
# In case you still want to use password authentication, you need to set the
# passwd/root-password-crypted variable. See below for further instructions.
### Usage
# We recommend to use the script to build an image with embedded
# preseed and other required files. In that case the preseed file gets loaded
# automatically and all additional files are available to the installer.
# In case you want to use a vanilla ISO image, please use the following boot
# instructions to load the preseed file (press ESC and enter in boot prompt):
# install auto=true priority=critical url=
# Note: you will need to adjust the "preseed/late_command" variable to match
# your environment in case you do not use the script.
