yes, i've actually been talking with on of the "debian guys" within mysql
about how this is a fairly common problem in real-world installations for
them as well. not only multiple instances, but multiple versions as well.
i'll probably be talking with him more about the details of implementing
this, but i'm sure the patch below would be a good first step since we'll
have to do this abstraction at some point anyway.
for a final version, i think we'll probably do something similar to what pitti
set up with the postgres packages, but i'm also not familiar enough with that
to know all the details of the implementation.
i'll take a look at the specifics of the patch the next time i'm sitting down
with the packaging, and maybe we can use this BR for general discussion about
this topic both in the meantime and until we get the full support.
