Hi swedebugia,

“guix build --rounds=N” builds the package N times if it hasn’t already
been built.  With grafts enabled this would be the graft derivation,
which isn’t very useful.

If the package has previously been built, however, it won’t rebuild the
package.  That’s why we have “--check”.

Using “--rounds” without “--check” is correct.  There should not be an
error or a warning in that case.
