One may argue that the 'make check' (or even 'make check-all')
tests could / should be allowed more resources than the pure
build environment.

[see above] Is it necessary to also run the 'make check' part in
that restricted environment? Or could that ('checking") not get
more priviledges?
Note that you can only run "make check" if you don't install
recommended packages, whereas more thorough testing would
include
make check-devel
or even
make check-all
but these do have quite a bit more requirements including
recommended packages being present.

Yes, that example should not have assumed a recommended package
to be available unconditionally.
I've changed it, thank you!
