But Karaf dev jbonofre then pointed out on <a href="https://github.com/apache/karaf/pull/196" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/apache/karaf/pull/196</a> that realpath as it's not available on most of Unix systems, so it was changed to readlink. That initially caused it to "now only works when invoked from current directoy, no longer via absolute path" (KARAF-4599).</p> <p>So with the latest patch set 10 in c/41305/ that's resolved too, so I think we'll have fixed this bug for good when <a href="https://git.opendaylight.org/gerrit/#/c/39982/10/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/39982/10/</a> is merged.</p> <p>beryllium --&gt; <a href="https://git.opendaylight.org/gerrit/#/c/42646/1" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/42646/1</a></p> Development External issue ID 6027 External issue URL Rank 0|i02r3z:
