Ubuntu Poised to Replace System V Init?
August 28th, 2006 Posted in General
upstart is a replacement for the init daemon, the process spawned by the kernel that is responsible for starting, supervising and stopping all other processes on the system.
The existing daemon is based on the one found in UNIX System V, and is thus known as sysvinit. It separates jobs into different “run levels” and can either run a job when particular run levels are entered (e.g. /etc/init.d/rc 2) or continually during a particular run level (e.g. /sbin/getty).
The /etc/init.d/rc script is also based on the System V one (and is in the sysv-rc package), it simply executes the stop then start scripts found in /etc/rcN.d (where N is the run level) in numerical order.
I’ll be following this one closely and possibly testing it on my stompbox.
