comments on insserv

Hi,

after (re)enabling insserv this week, I thought I'd share my
experiences. insserv successfully installed and reordered the boot sequence.

I attached the diff stat (thanks to etckeeper) after the conversion.

And rc2.d and rc6.d after the conversion:

A few comments/observations

1.)

I checked the diffstat for copied lines:

#	copied:     rcS.d/S48console-screen.sh -> rc0.d/K05console-screen.sh
#	copied:     rcS.d/S75sudo -> rc0.d/K06sudo
#	copied:     rcS.d/S40networking -> rc0.d/K11networking
#	copied:     rcS.d/S08hwclockfirst.sh -> rc0.d/K20hwclockfirst.sh
#	copied:     rcS.d/S48console-screen.sh -> rc1.d/K05console-screen.sh
#	copied:     rcS.d/S75sudo -> rc1.d/K06sudo
#	copied:     rcS.d/S48console-screen.sh -> rc6.d/K05console-screen.sh
#	copied:     rcS.d/S75sudo -> rc6.d/K06sudo
#	copied:     rcS.d/S40networking -> rc6.d/K11networking
#	copied:     rcS.d/S08hwclockfirst.sh -> rc6.d/K20hwclockfirst.sh

This probably means, the LSB header information is not in sync with the
information that is passed to update-rc.d

Example: console-tools.postinst has
  update-rc.d console-screen.sh start 48 S .
But the LSB header has
  # Default-Start:     S 2 3 4 5
  # Default-Stop:      0 1 6

I'd assume, those LSB headers are not entirely correct. I'll leave it up
to Petter to decide and file bug reports.

2.) The start/stop priorities have strange "holes".
Take ls /etc/rc2.d
The first start priorities are
  S15,S16 [*no* 17,18],S19,S20,S21,S22, [*no* 23], S24
Why does it start at 15 at all, and not S01? Why are some start
priorities missing?
Similar issue in /etc/rc[06].d/
There
K02,03,04,05,06,07,08,09,10,11,12,13, [*no* 14,15,16],17,18, [*no* 19],
20,[*no* 21],22,23,24
Some questions here: Why is there no K01, why are those "holes" in the
sequence?

3.) console-setup is not started after console-screen.sh anymore.
I installed console-setup to configure my console font and keyboard
layout. In the old init sequence, console-screen.sh was run at S48,
console-setup S49.
Now console-setup is S19, console-screen.sh S20, so my changes get reset
by console-screen.sh again.
=> I'd say console-setup should be fixed to run after console-screen.sh
Again, I'll leave it up to you to file a bug report and request the
correct action (as I don't really know what's the right thing to do).

4.) Imho you should not only divert update-rc.d, but also it's man page.
It's weird when update-rc.d and update-rc.d.8 are out of sync.
The man page of update-rc.d-innserv is insufficient at its current state
though. A lot of vital information is missing (e.g. how to disable
services with insserv).

So, that's it. Hope this comments are useful.

Cheers,
Michael
