I'm not 100% sure of this but it looks to me like Sun really doesn't
have to do anything to "support" dataless because there's nothing
to do, except to make sure they continue to structure /usr and /var
so that /usr can be mounted read-only and /var (or root) is where any
machine specific files go.
All you have to do to create a dataless environment is to setup
a server with the complete Solaris installation. Then, install
the "End-User' Solaris configuration on a to-be-dataless client.
After the machine reboots, simply modify /etc/vfstab to mount
/usr over NFS from another machine. (You will need a statically-linked
route program if your server and client are on different subnets).
Once this works then you can wipe-out the local /usr and use it
for whatever you want.
I admit doing things this way might not be as elegant as when using an
officially supported method but it works now and will continue
to work in the future, barring major changes
Am I missing something?
