> Different locations for KARAF_HOME and KARAF_BASE
> -------------------------------------------------
>
> Key: KARAF-4005
> URL: https://issues.apache.org/jira/browse/KARAF-4005
> Project: Karaf
> Issue Type: Bug
> Components: karaf-core, karaf-instance
> Affects Versions: 4.0.1
> Reporter: Markus Rathgeb
> Assignee: Jean-Baptiste Onofré
> Fix For: 4.0.2
>
>
> I would like to change the directories for KARAF_BASE, KARAF_HOME, KARAF_DATE
> and KARAF_ETC.
> Using separate directories for KARAF_BASE and KARAF_HOME result in error
> messages on start and stop of the Karaf container (I shortened the path):
> * Unable to update instance pid: Child instance started but no root
> registered in /home/maggu2810/.../karaf/home/instances/instance.properties
> * Unable to update instance pid: Child instance stopped but no root
> registered in /home/maggu2810/.../karaf/home/instances/instance.properties
> The class org.apache.karaf.main.InstanceHelper is using:
> final boolean isRoot = karafHome.equals(karafBase);
> If the properties are empty and isRoot is false, this error message and an
> IllegalStateException is thrown.
> So, IMHO the intention of that variables is to support using different
> directories. But this seems to be broken (do not run in a problem at runtime
> after a short test, but the code throw the exception).
> [http://karaf.922171.n3.nabble.com/Custom-distribution-change-directory-layout-tp4042677p4042691.html]
> "The purpose of the current variables is more to be able to adapt to your
> machine/administrator constraint: put KARAF_ETC in /etc/karaf, put KARAF_BASE
> in /var/karaf and KARAF_HOME in /home/karaf for instance (by moving the
> directories)."
> I checked in an example, so you could easily reproduce it:
> repo: [email protected]:maggu2810/karaf-custom-distribution.git
> branch: dir-layout
> Build it and test the custom artifact.
