But in general, I agree, this is insane requirement as nobody would ever think of it in Windows. Not happy w/ a traditional Unix permissions? Go for ACLs. The only pity is that the current Posix-draft hack widely used on all Linuxes is a mess and Rich-acl support is still nowhere in sight :-( Ondrej On 10/26/2012 09:07 AM, Natxo Asenjo wrote: <blockquote cite="mid:CAHBEJzVb2CkdMdMx-5y9L8rVbBmet48W0xapRJpxr-L8MHBmxw@mail.gmail.com" type="cite"> <pre wrap="">On Thu, Oct 25, 2012 at 9:11 PM, KodaK <a class="moz-txt-link-rfc2396E" href="mailto:sakodak@gmail.com"><sakodak@gmail.com></a> wrote: </pre> <blockquote type="cite"> <pre wrap="">We have many different development groups, but people can be members of multiple groups.
