Hi,
I'm using 9.0_RC1, so I don't know if this is a functionality that was used
in the past and then dropped or will be introduced in the future.
At one point in time, probably around 10+ years ago, Red Hat introduced User
Private Groups [1]. I ignore if other OSes have had this feature before
(probably Mac OSX ?). Anyway, this has then spread to all other major Linux
distros. FreeBSD calls them "unique groups" [2]. OpenBSD has this line in
/etc/usermgmt.conf:
group =uid
I never understood how this would be usefull
[I forgot to cc: the list. Manuel, sorry for the duplicate]
I wonder how this can possibly _not_ be useful.
On a multi user system, all files are created readable by the group (umask
022). If we are all in the same group, anybody can read my newly created
files (imagine a local password file for alpine or ssl certs for irc, etc).
It's then left to the user to change umask and/or adjust permissions. Why
not just make it easier for the user?
Note that it's also readable by others (with umask 022, the files are
created rw-r--r--), so changing the group won't help.
