Package: adduser Version: 3.112+nmu2 Personal groups are the default on Debian. The purpose of personal groups is to allow users to run with a umask of 002 so that they can sensibly access shared filespace areas whose access is controlled by group.
This only works if the shared filespace areas remain owned by the relevant group. This is best achieved by setting the g+s bit on all directories which are part of shared filespace areas. This both ensures the right ownership of newly created files and directories, and propagates the g+s bit to subdirectories. With personal groups, the user's home directory is owned by their personal group so the g+s bit has no effect in that case, other than (a) to ensure that all the subdirectories they create are also g+s (b) to ensure that files they create in their filespace become owned by their personal group regardness of their process's primary group. If the user wants to make a shared filespace area, the natural approach would be: chgrp -R shared-group directory If the directories in question are not g+s, this is not sufficient; a rune to turn on g+s for the relevant directories is needed. If the home directory areas were g+s this would not be necessary. So in the default (personal groups) configuration, home directories should be g+s.
