comment References about Hasse diagrams of root systems
This paper arxiv.org/abs/1306.1593 by Ringel describes the posets for all the classical types, and has nice pictures for the exceptionals.

comment Laurent and power series over the field with one element?
Dyckerhoff's paper arxiv.org/abs/1505.06940 says that finite $\mathbb F_1[[t]]$-modules should be considered as an $\mathbb F_1$ vector space (i.e. finite set with distinguished element $*$) together with a nilpotent endomorphism. (I guess this is a different paper from the one @darijgrinberg was looking at; the parts of the partition arise here as lengths of maximal paths to $*$.)
