Plymouth is an application that runs very early in the boot process (even before the root filesystem is mounted!) that provides a graphical boot animation while the boot process happens in the background.
It is designed to work on systems with DRM modesetting drivers. The idea is that early on in
... [More] the boot process the native mode for the computer is set, plymouth uses that mode, and that mode stays throughout the entire boot process up to and after X starts. Ideally, the goal is to get rid of all flicker during startup. [Less]

Faster is a very little init script aimed at Linux power-users and geek stuff oriented people. It is not industrial strength and does not comply with any other buzzwords.
What it really does well is providing the fastest boot times you can achieve in you machine under normal conditions.
It
... [More] provides you a normal initialization process and then exits granting control to any daemon manager you choose (About 2 to 5 seconds to the login prompt depending on your machine power and disk pollution)
It is compatible with any POSIX shell (tested with busybox ash and dash) and a little distribution agnostic. Does not rely on additional dependencies.
Mostly a successful personal proof of concept which I deploy in any machine I have access to. Please visit the home site for more information. [Less]
Tool to report actual VM boot times
This tool utilises communication between the host Linux distribution and the guest Linux distribution by way of a socket, measuring the actual start time from the very moment the process is invoked, up to the point the system is fully booted and usable (as
... [More] determined by its own profile and service configuration)
It can be used to start many VMs in parallel to identify bottlenecks and assess systems performance, both guest and host, as well as detailing total boot time for multiple VMS and the average.
Each report is also accompanied by the internal concept of boot time (as made available via systemd-analyze) so that the delta between real boot and VM internal boot can easily be seen. [Less]
