As some one who lives with polyinstatiated namespace /tmp, The only
problem I know of now is handing of kerberos tickets. Whenever a system
process (root) needs to communicate with a user via /tmp. namespace
/tmp breaks it. sssd can not create kerberos tickets in my /tmp and
gssd can not find my kerberos tickets in /tmp. I believe the solution
to both is to move the tickets to be managed by sssd and leave /tmp to
users.
BTW, X has solved this problem a couple of years ago by using virtual
namespace for its sockets.
In the abstract namespace, don't you have the same problem where if the
real X server dies for any reason, other users can create a socket at
the same path and mess with your applications?
