SysV init It has been the system that has been linked to Linux from the beginning, and linked to the Unix world, although others like BSD (and even some distros) used their own. Furthermore, there have also been some implementations like Ubuntu's Upstar. With the arrival of systemd everything changed, and most distros adopted it, becoming the default system, with the exception of some distros like Devuan that continue to use SysV. Well, now comes Finit, to make the choice even more complicated ...
As you know, many have embraced systemd no problem, but there are still naysayers who still prefer SysV init or others. Now, Finit comes as a simple replacement for both SysV init and systemd. And with the Finit 4.0 version, you will be able to enjoy some improvements that make it even more interesting as an alternative to these.
Finit comes from Fast Start, and is based on SysV init, and developed to be fast and lightweight as the name suggests. In addition to executing and managing startup scripts, it also has process monitoring similar to the runit daemon. And, of course, it integrates seamlessly into GNU / Linux distros, specially designed for the most minimalists.
It is fully functional for both the server and the desktop. It is also capable of start services in parallel, monitor and automatically restart those that fail, provides great ease of use, has a simple configuration file, etc.
As for the Finit 4.0 version, the news included are:
- Initial support for cgroups v2.
- The standalone restart tool has been replaced by a symbolic link to initctl, like its siblings: halt, poweroff, shutdown, suspend.
- Removed built-in inetd super server. If you need this functionality, use an external inetd, such as xinetd, instead.
- Terms of service change from to , which is more intuitive.
- Support for SysV start / stop scripts and branch service monitoring.
- Redirection of dbus daemon output to syslog.
- initctl, without an argument or option, now defaults to the list of services.
