I understand that this patch is pretty old.<br />But, we having issues because of it.<br /><br />According to the description it is intended to fix some problems for RPM systems.<br />We are using DEB packages and this patch is preventing to update rc.d scripts if new version of the package has updates in it.<br />Particularly, the new script is intended to be run with a different boot priority: 'start' directive to update-rc.d.<br /><br />The problem is that during upgrade an old symlinks to rc* directories are not removed because of this condition added by wrap_uninstall().<br />And as a result update-rc.d is failing to update init scripts in rc* folders. Because old are existing.
