It is useful sometimes to call it in pkg_postinst(), if the user/group
is needed at runtime and not during install-time.

What difference is there if you run it during setup vs postinst?

If the build fails or user aborts the merge, his/her system
is not junked with an unnecessary account/group.

this is why we allow people to pick the appropriate step. ebuilds should be
using pkg_{pre,post}inst unless the user/group is needed at src_* time.

I noticed a rather annoying test inside enewuser for existence of the
provided "shell" path in the filesystem ( user.eclass lines 153-156 ).

If you want to create an user and set the shell variable to an program
you just emerge, you have to call it from pkg_postinst.

(The example was a trivial desktop manager x11-misc/trivdm in [1])

If you don't need it in install-time (i.e. don't install any files
owned by it), you should indeed defer the check as late as possible.
There's no point in creating user earlier when the emerge can still
fail/be aborted.
