Hmm. You do have a point here, because with the patch it is possible to
do something like stupid like "stap -P foo.ko bar.stp".
We should consider separating the compile / run front-ends into
separate programs entirely, perhaps by promoting and renaming stpd
("staprun")? This makes sense further because we will want to make it
possible to install only a small subset of systemtap itself on a
deployment machine in order to run a pre-compiled script.
Hmm. That's an interesting idea. If we were to do that, we might think
about unifying option names between the two programs. Currently, we've
got functionally equivalent options named different things between the 2
-x pid -t pid
-s size -b size
I'm unsure about separating the programs. I don't have a strong feeling
Why not "-S [dir]" so that the current directory is the default?
That is certainly possible [...]
Actually, not really, with getopt. A flag must or must not take a parameter,
otherwise it leads to parsing ambiguities.
