It is sometimes desirable to package debugging information that is a subset of
the original data. The subset would need to be just enough to run some
systemtap scripts. One may want to ship just a subset because the full
debuginfo would be proprietary, or just too darn big.
Here's one way to do it:
- let the interesting part of the application be defined by a collection of
systemtap scripts (and the tapsets they use)
- extend systemtap / elfutils to be able to mark all parts of the debugging
files actually used - at as low as a DIE granularity
- develop a tool to take such markings, and excise all unmarked parts of the
debuginfo. it may be simplest to zero-fill the unused parts, then compress the
resulting file.
- extent systemtap to look for such subsetted debuginfo files in another path,
using elfutils path settings already available

We probably won't write something quite like this,
with the lossless compression work already in progress.
