Is there any way to deliver updates for fragments with OSGi hooks?

Lets say I have developed OSGi hook and it is included into feature available from my update site. I have configured p2 touchpoint to add

-Dosgi.framework.extensions=reference:file:org.domain.feature_1.0.0.vXXXXXXXX-XXXX.jar

into eclipse.ini to activate my hook when eclipse restarted after installation.

But there are several problems with this approach:
1. How do I deal with scenario when there is another hook(s) already configured in eclipse.ini?
2. If i need to deliver update for a fragment with OSGi hook implementation how do I update my fragment reference in osgi.framework.extensions system property?

p2 recognizes this itself so there's no touch point needed - it will
push the information into the config.ini! At least this works for me
flawlessly for e(fx)clipse updates.

I only had one problem lately which involves Kepler SR 1 and the
p2-directory app which does not update the config.ini.

Tom,

do you mean when I fix the problem and build new version I don't need to do any efforts to update reference to hook's jar in config.ini?

Does this work in luna?

Thanks

Tom,

Do you know of any docs for this and how does it work if there are two plugins wanting to install osgi hooks ?

i.e. e(fx)clipse and jbosstools both add hooks ?

are you saying that p2 will recognize and configure the osgihook's without any touchpoint at all ?

Right you don't have to adjust the eclipse.ini because p2 will add the
information to the config.ini automagically!

I would at least hope it would - I can't provide you with docs and was
suprised myself that p2 figures this out itself.

I guess easiest is propably to locate the hookconfigurators.properties
string in p2 source because this is the only way it can detect the
bundle is a hook one.
