As long as no more than 16 groups perprocess are used, no changes should be visible. When morethan 16 groups are used, old binaries may fail ...

I used to add users to a new unix group by firing up my favorite editor and edit /etc/group. That’s because I always forget which tool to use and how to use it. This blog posting shall remind me of usermod: usermod -a -G [,,…]
