Patches welcome. If you decide to implement this, make sure that the
code is only active with a running sysvinit (ie, don't affect chroots).
It is not trivial, which is why I didn't implement it myself. You
probably need to integrate ucf to handle all the corner cases.
Patch attached. I haven't gone through all the steps of integrating ucf
- the disable autospawn file isn't currently marked in the package as a
conffile, so this patch, while it works in my limited testing, could
still be improved on there.
LMK what you think - if you're happy with this approach and will
integrate it, I can work on ucf integration as well.
