If you never use the upgrade-X script to update the packages on
your Nevada system to the latest build, stop now and hit delete.
If you do, and you remotely display applications directly to your
X server, instead of using SSH X11 forwarding (and if you do, why
not try ssh? it's free and easy!), then the fix for 6715804 will
require you to re-enable TCP connections to the X server after
running upgrade-X.
Since upgrade-X doesn't preserve SMF settings for the X services,
just deletes and recreates them as part of the pkgrm of old
packages and pkgadd of the new versions, running upgrade-X will
restore all settings to the default values in the SMF manifests.
Previously, this meant even if the installer set you to Secure
by Default mode or you'd run netservices limited, upgrade-X would
re-open the TCP ports on the X server. Starting in X build nv_93
the default value in the x11-server SMF manifest has changed to
disabling TCP ports and you'll need to re-enable after upgrade-X
if you need them.
To enable or disable, use svccfg:
svccfg -s x11-server setprop options/tcp_listen = true
(If like me, you can't remember that command, just remember
"man Xserver, and search for svccfg".)
