Simon,
No, there's nothing for that yet. Aren't the contents of that folder
signed and therefore shouldn't be modified?

Simon,
Yes, I'm not really sure how signatures work on the Mac either; I know
they changed the layout in Mars so that signatures work properly...
Your forum edit doesn't show up in my Thunderbird reader but I see
you're referring to
https://wiki.eclipse.org/EPP/Logging#Enable_additional_debug_output
I can't really understand how they define what ${eclipse.working.dir}
means for all platforms, i.e., for Mac it suggests, as you say, that
it's in the same folder as the executable (though it's wrong in the
document and should be ./Eclipse.app/Contents/MacOs/.options), but it
doesn't define where this is on Linux or Windows, presumably the same way...
It seems rather questionable to me because with a shared/read-only
installation such a location is read-only. I would have expected such
information to be stored in the configuration folder so that for a
read-only installation the user can have a place to modify it. I need
to find out more details about why it's this way, but I suppose it's
unlikely to change anymore...
Reading more about this, I wonder if your assumption might just be
wrong. In particular, from reading
http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.platform.doc.user%2Ftasks%2Frunning_eclipse.htm
and looking at the documentation for the -debug flag it says:
If a file location is not given, the platform looks in the directory
that eclipse was started from for a file called ".options".
I think that means it looks in the folder specified by user.dir system
property, i.e., the current working directory. That just happens to be
the folder where the executable is located when you launch from an
icon/shortcut/app, but that's not generally the case. So if you really
want it always to use certain options, you should specify an Eclipse
Ini task to specify the -debug option and include in that task the
absolute location of the .options file.

From a command-line, the current directory of the shell/command-line
process should remain the current directory of any launched executable.

An Eclipse Ini task can have Vm either be true or false. In this case,
the -debug option is not a VM option. Of course if you are going to
provide such a task to set the -debug option, it's also easy to specify
where the .options file appears, i.e., you might specify
${user.home/.../.options) and have another task to puts the option you
want into that file... This way there is a single options file that can
be changed for all installations...
