Hi,

What do you think about a patch to fork dspam into the background ? If I
enable dspam in daemon mode then the next update the package won't get
installed without hitting Ctrl-C. The manpage of start-stop-daemon says
this about --background:

- -b|--background
    Typically  used  with  programs  that don?t detach on their own.
    This option will force start-stop-daemon to fork before starting
    the  process,  and  force  it  into  the  background.   WARNING:
    start-stop-daemon cannot check the exit status  if  the  process
    fails  to  execute for any reason. This is a last resort, and is
    only meant for programs that either make  no  sense  forking  on
    their  own, or where it?s not feasible to add the code for it to
    do this itself.

Well, a simple:
if (fork()) {
  exit(0);
}
will work.

Regards,

Matthijs Mohlmann
