>From a small lab size setup I am managing with warewulf diskless, the
compute nodes have a minimal set of rpm installed, but if the users want
to have the "same" environment as the login node, he can just
singularity shell into it. That works for me too when I need to build
on the faster compute nodes than on the login node and that gives me
a takeaway build container wherever I need it.

just my 2 cents
