Also when I want to remove insserv, aptitude asks Remove the following packages: 1) initscripts [2.88dsf-59.8 (now, unstable)] 2) sysv-rc [2.88dsf-59.8 (now, unstable)] 3) sysv-rc-conf [0.99-7 (now, unstable)]
Which seems dangerous... http://unix.stackexchange.com/questions/214155/completely-remove-remains-of-sysvinit "Be aware that initscripts is not sysv specific, removing it will almost certainly destroy your system." OK thank God me and anybody reading this bug did not remove insserv.
