8 That was the idea, RH did it that way a dozen
9 years ago for exactly the reason you mention:
10 dir mods of 02770 make it easy to share files
11 but require 002 umask. Fix was to set the
12 per-user group, allowing private dir's (largely
13 $HOME) to have tighter mods with files below
14 them "group readable" by a single-user group.

16 The scheme works rather nicely in nearly
17 every situation (POSIX ACL's play hell with
18 the scheme, but, then, they are supposed to).
