This makes it possible to fully automate most types of installation and even offers some features not available during normal installations. More informations on [Debian wiki][preseed informations].

lv_free - /mnt/free
: The preseed's partitionning need to allocate all the disk space. If it's not define, it will put it in the last defined partition all extra free space. So **lv_free** is a temporary LV that you can destroy and use the space to resize any other LV.
