This is the release of the classic sysvinit 2.99 init system, which was widely used in Linux distributions in the days before systemd and upstart, and now continues to be used in distributions such as Devuan, Debian GNU/Hurd and antiX. At the same time, the release of the insserv 1.23.0 utility used in conjunction with sysvinit has been released (the version of the startpar utility has not changed). The insserv utility is designed to organize the boot process, taking into account dependencies between init scripts, and startpar is used to ensure that several scripts are launched in parallel during the system boot process.
The new release of sysvinit has updated the man pages and fixed typos in the code comments. There are no functional changes in sysvinit other than documentation and improved code readability. Insserv has been redesigned handler that extracts information about start and stop levels from script LSB headers. The change solved the problem with erroneous definition of runlevel in some Debian packages when specifying empty values ββin the Default-Start and Default-Stop parameters.
