A container is an isolated system with a separate root file system and
operating system userland. The containers share a common operating system
kernel.
+
+ LVM
+ Logical volume manager. The LVM allows to allocate space on block
+ devices more dynamically than with traditional partitions. The block
+ devices are managed as physical volumes (PVs) that are grouped in volume
+ groups (VGs). Space can be allocated as logical volumes (LVs) that can be
+ formatted using regular file system tools. LVs can be resized without
+ reboot. LVM provides snapshot functionality that is useful for backup and
+ upgrade procedures.
