[SunRay-Users] Accessing Linux (TS-style) Desktops from a current VDI environment

Just to back this up we recently rolled out the 3.2.2 VDI maintenance
release and our custom kiosk sessions were untouched throughout the
upgrade process.

But I too was worried about the upgrade damaging them however I could
not find the documentation I "thought" I remembered reading about custom
kiosk sessions so I assumed it was already removed.

But perhaps I don't read the docs all the way through anyway?  ;-)

No, VDI just uses the default kiosk session type, and does nothing to 
the individual tokens that may be overridden.

VDI will overwrite the default kiosk session configuration for you, but 
it won't overwrite alternate session configurations.

I think the VDI 3.0 may have had that caveat that it was for VDI 
delivery only and don't make changes kiosk mode, but I don't believe 
that applies any longer.  The only thing that still applies is that the 
primary shouldn't host sessions (best practice anyhow for bigger Sun Ray

FOGs).

If you find a pointer in the doc, that suggests this, let me know.  I'll

fight to get rid of it.
