I don't understand where the bug is.
If you install a fragment, either you add it to a feature somehow, or you
add it to the etc/startup.properties.
In the first case, the pax-logging bundle has to be refreshed. Else, the
fragment won't be wired to the bundle.
This may lead to the console being restarted, and that's not necessarily a
problem.
Note that the above should only happen at the first boot.
A work around would be to generate a custom karaf distribution and make
sure that fragment bundle is part of the startup phase, in which case it
will be added to the etc/startup.properties and be correctly installed in
the very first startup and the need to refresh the pax-logging service
bundle should go away.
