  In theory, none, but --schedule-only is a little bit of a hack and I
don't personally use it, so I can't tell you whether it'll work in all
circumstances.  For instance,

  aptitude in command-line mode doesn't like continuing with broken
dependencies, even where the interactive UI would let you save your
state for later.  You should be able to get it to continue by passing
the "-y" flag to accept the first solution (but that obviously doesn't
work if you don't want the first solution).  You could also pass a
full solution on the command-line, although there might be issues if
you have different conflicts on the different computers.
