Some packages have inconsistency between the init.d script headers
used with dependency based boot sequencing and the runlevels specified
on the update-rc.d command line and used by the legacy boot ordering.
Such inconsistency is most likely a bug in the package, as the two
ways of ordering init.d scripts should enable and disable the scripts
in the same runlevels while Debian migrate to dependency based boot
Such inconsinstency is reported like this when a postinst script call
update-rc.d: warning: initdscript start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (S)
update-rc.d: warning: initdscript stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (none)
Such reports are most likely bugs in the package calling update-rc.d,
and should be reported and fixed in the individual packages.
See the paragraph "How to solve migration problems" at https://wiki.debian.org/LSBInitScripts/DependencyBasedBoot for information how to fix these issues.
The commandline to find these logs is:
COMMAND='grep -E "update-rc.d: warning.*do not match LSB|service.*already provided"'
