InitNG stands for Next Generation Init System ( German initialization system of the next generation) and is a software system for Unix and Unix-like operating systems for initializing the operating system. Initng is a complete replacement for the outdated init system SysVinit which by most Unix and Linux - distributions is used.
background
InitNG was founded by Jimmy Wennlund and is being actively developed by him and a few others.
Like its predecessor, InitNG is the process that is started first by the kernel and is therefore given process ID 1. This first process starts all required system services based on the desired runlevels .
SysVinit always starts the processes in a predefined order and only starts a process when the previous process has been completely initialized. InitNG, on the other hand, starts a process immediately when all processes on which it depends have been completely initialized. So it can z. B. After the network has been initialized, Apache, database and mail system can be initialized in parallel (for comparison SysVinit: first network, then Apache, then database, then mail system ...). This parallelization of the individual scripts results in a significantly higher speed compared to SysVinit.
Another problem with the predecessor is that it does not provide any information about the status of the boot process . Among other things, it makes the use of displays, so-called bootsplashes with progress display, only possible to a limited extent. InitNG should provide a remedy there.
InitNG can restart services that have crashed if desired. This is an important feature for server systems that have to run continuously. A real warm start is also possible with InitNG, whereby all system services are shut down and then restarted immediately.
