Systemd vs sysvinit
What are the advantages/disadvantages of using systemd versus sysvinit?
systemd: - Fast boot time, mainly achieved due to starting services in parallell. This can also be achieved with SystemV init, but has to be done manually, while it is a product of dependency handling on systemd. - Automatic dependency handling. - Monitoring of started services with the ability to restart crashed services. - Modules written in compiled languages, probably hard to debug. - Tries to replace several system services, from the actual init over hardware recognition and session management to the logging service, and many more. Not the Unix way. - https://wiki.archlinux.org/index.php/Systemd - http://freedesktop.org/wiki/Software/systemd
SystemV: - Boot time depends on the admins optimizations. - Due to its static dependency handling relies on a knowledgeable admin. Decide for yourself if you count that as advantage or not. - Needs often some hacks to monitor services, services can easily escape the monitoring. - Written as Shell scripts, so easy to debug and alter if necessary. - Minimal approach, doesn't try to be the one super-service running the system. - https://wiki.archlinux.org/index.php/SysVinit_%28Italiano%29
