if i log in as dhorner and type groups it says i am in one set of groups
but if i type in
groups dhorner it says i am in other groups. so is there a difference in
me as a user and me as process i am in? THese file privs has always
driven me nuts. In a dir if i own the diri can add a dir or save a file
here but if i am part of a group that owns the dir i cant. What is the
def truth about who can use a dir?
