I don't know why it was originally adopted, but I can tell you why I think it's a good idea. If you're working on a shared project with another user, you'll want to make sure those files are group-writeable. If you have all users in the same group, then it's not safe for any user to have umask 002 by default, because everybody will be able to write to all the files in their home directory. On the other hand, they'll have to remember to use umask 002 when working on shared files, because otherwise those files will only be writeable by them. With one group per user, umask 002 is safe. All the files in your home directory can be group-writeable, and it makes no difference - but when you go to work on a shared project you don't have to remember to switch the umask over. (Another answer to this problem is "use CVS", granted, but I don't think revision control is appropriate for each and every shared project.) > 2.

Go ahead, although personally I'd create a new group. -- Colin Watson [EMAIL PROTECTED]
