Package: sysv-rc Version: 2.88dsf-13.1 Severity: critical Justification: causes serious data loss
Blindly enabling insserv can result in unbootable systems or systems which boot but don't start all services. sysv-rc.postinst currently states that enabling insserv is "recommended", with no mention of the possible severe consequences. This bug is critical rather than grave because the lost data - the Snn and Knn values - cannot be recovered without restoring a backup. (In fact it's slightly worse than that - if you merely restore /etc insserv will eat it again. You have to use undocumented magic to prevent this.)

The boot system is prepared to migrate to dependency-based sequencing. - This is an irreversible step, but one that is recommended: it allows - the boot process to be optimized for speed and efficiency, and provides - a more resilient framework for development. + This is an irreversible step - restoring your /etc will not undo it.
