I am not sure about that. My second pull request, against zm-launcher,
takes care of the permission issue. To summarize: The gc.log (and with
rotation gc.log.0.current) is created with the owner root:root because
the JVM will only later drop privileges to zimbra:zimbra. Some code in
zmmailboxdmgr will fix this up but only for gc.log. It looks like it
works with the wrong permissions as well but I didn't do much testing
and thus either the permission issue is not an issue at all or it might
break your setup in interesting ways.
Fortunately it isn't hard to build a patched zmmailboxdmgr. Just
checkout the zm-launcher repo with my patch applied (until it is merged
you can find it in the branch bugfix/bz-98011-use-gc-log-file-rotation
in https://github.com/mss/zm-launcher) and build the zmmailboxdmgr:
git clone https://github.com/mss/zm-launcher.git
cd zm-launcher
git checkout bugfix/bz-98011-use-gc-log-file-rotation
make all JAVA_BINARY=/opt/zimbra/common/bin/java
This will create the file build/zmmailboxdmgr which you can then place
on your system.
YMMV and if anything breaks it isn't my fault and you may keep the pieces.
Cheers,
Malte
