[CentOS] Upstream vendor's diskless vs LTSP

Hello all, I have a customer that insists of using upstream vendor's diskless (system-config-netboot) rather than LTSP. The reason is that he wants to use a 100% packages from the vendor, not from LTSP or any other party.

I try the vendor's diskless system, and although it's very simple to setup, it lacks the support and/or documentation whereas LTSP is very good in it. Another sample is that he wants to connect a scanner to the client, I doubt it can be, since there's no documentation about it at all from the vendor.

Is there any fundamental difference between the two setups? Thank you.
