Hello all,
I have tried to build Mono 5.20 without bootstrap, but it does not seem to be possible.
see https://github.com/mono/mono/issues/15643 and https://bugzilla.redhat.com/show_bug.cgi?id=1697526
I have now created a change for Fedora 31: https://fedoraproject.org/wiki/Changes/Mono_5_20
I hope it should not be as disruptive as the change from Mono 4 to Mono 5.
All the best, Timotheus
