Minimal and client VM for jlink?

[Nicolai Parlog]

 Hi David,

thank you very much. However much I search, I rarely end up finding this
stuff myself (even "java se 9 vm client server minimal" doesn't do the
trick).

Maybe the jlink documentation and/or --list-plugins output could mention
that, e.g. by adding that link?

 so long ... Nicolai
