Re: sysvinit backward compatibility in upstart .5

 Hi,

 I downloaded the upstart (.5) code from trunk. I was able to get the 
 sysvinit backward compatibility going with upstart (.3.9). I am trying 
 to do the same with the code in trunk.

 I notice that runlevel, telinit etc are not yet implemented. Are there 
 plans of implementing them? If they will be implemented, is the plan 
 to use the existing socket interface for telinit to talk to upstart or 
 will that be replaced by dbus. In which case, dbus should be started 
 pretty early in the startup sequence.

 In the mean time, what are the alternatives I have to achieve the 
 backward compatibility with sysvint?

  

 Any suggestions are welcome.

  

 Thanks and Regards,

  

 Sandeep

They will be implemented, and in fact are. They currently reside in the 
dbus-userspace branch on launchpad, but merging is imminent. There 
should be a release soon with all of this in place.

 Is it possible to implement SysV compatibility without using D-Bus 
 messaging?
 Meaning basically using the starting/started/stopping/stopped events 
 of a set of SysV compatibility jobs themselves.

   
   
 Not all of it and not easily. But then, why do you need to 
 emulate sysv at all?
 
 Well we do have quite a bit of legacy software that have not yet moved
 to Upstart style jobs.

 Can you help me understand which part is not possible?

Well, you wouldn't be able to use telinit, which makes it hard to tell 
the system to shut down or reboot or really do anything.
