Why exactly? Since it's only a char and not char[] I don't see the
disadvantage over int or a define or whatever. Of course I could always

Use-case is to isolate process information from other users' or groups'
eyes, e.g. with 550 the output of ps aux only lists processes of the
groups your user is a member of.
