[PATCH v2 0/3] initscript: add support for uprobes scripts

[Jonathan Lebon]

Hi Stefan,

I'm wondering, could we do without the user needing to
provide the -u option at all and make it completely
transparent instead?

I.e. the initscript could always use the new
--save-uprobes switch, and remember whether uprobes.ko was
built or not so that at runtime, it appropriately appends
-u to the staprun command.

This also works around overriding the '-u' option in the
config file, which could previously be used to enable
unoptimized mode.

The only question is how/where this setting would be
remembered. One way I can think of right now is to simply
touch a blank file in the CACHE_PATH's uprobes directory for
each script that requires it, but maybe there's a more
elegant method.
