Appendix B. Automating the installation using preseeding B.4.8.3. Controlling how partitions are mounted Warning B.4.9. Base system installation Normally, filesystems are mounted using a universally unique identifier (UUID) as a key; this allows them to be mounted properly even if their device name changes. UUIDs are long and difficult to read, so, if you prefer, the installer can mount filesystems based on the traditional device names, or based on a label you assign. If you ask the installer to mount by label, any filesystems without a label will be mounted using a UUID instead. Devices with stable names, such as LVM logical volumes, will continue to use their traditional names rather than UUIDs. Traditional device names may change based on the order in which the kernel discovers devices at boot, which may cause the wrong filesystem to be mounted. Similarly, labels are likely to clash if you plug in a new disk or a USB drive, and if that happens your system’s behaviour when started will be random. # The default is to mount by UUID, but you can also choose "traditional" to # use traditional device names, or "label" to try filesystem labels before # falling back to UUIDs. #d-i partman/mount_style select uuid There is actually not very much that can be preseeded for this stage of the installation. The only questions asked concern the installation of the kernel and the location of the base pre-configured filesystem for the installation. Setup of the /etc/apt/sources.list and basic configuration options is fully automated based on your installation method and answers to earlier questions. You can optionally add other (local) repositories. # Configure a path to the preconfigured base filesystem. This can be used to # specify a path for the installer to retrieve the filesystem image that will # be deployed to disk and used as a base system for the installation. #d-i live-installer/net-image string /install/filesystem.squashfs # Configure APT to not install recommended packages by default. Use of this # option can result in an incomplete system and should only be used by very # experienced users. #d-i base-installer/install-recommends boolean false # The kernel image (meta) package to be installed; "none" can be used if no # kernel is to be installed. #d-i base-installer/kernel/image string linux-generic B.4.10.
