I am distributing packaged files in ZIP format. I use the following to create:
zip -r distr.zip files/
When expanded on other UNIX system files preserve their permissions as they were when I packed them. I am willing to avoid storing permission information.
My question is: Is it possible to do so? I'm using info-zip 3.0
The problem is that on my system i use umask 0002 and files are writable for groups. However when expanded on other systems, groups write permission is not desired. I could remove group write permissions, but then it wouldn't work on my system.

Alternately, if you want to use a zip file, you might want to try creating it with a different program. For example, Apache Ant gives you full control over the permissions of files and directories it zips up - http://ant.apache.org/manual/Types/zipfileset.html has details. For example, you could do something like:
