systemd
O que é?
systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts.
systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux
cgroups, supports snapshotting and restoring of the system state, maintains mount and
automount points and implements an elaborate transactional dependency-based service control
logic. It can work as a drop-in replacement for sysvinit.

BoxGrinder
O que é?
Ferramenta para gerar imagens (appliances) de máquinas virtuais, personalizando a instalação,
determinando que pacotes serão instalados e executando tarefas pós instalação.
Gera o appliance sem intervenção, nos formatos RAW, vmware e ec2, que podem ser usados pelo
KVM, VmWare e pelo serviço de cloud da Amazon, respectivamente.
