+Subject: [PATCH] Pass package_types to dnf base group_install as tuple, not
+ set
+
+I believe this is probably the cause of
+https://bugzilla.redhat.com/show_bug.cgi?id=1886567 , which broke
+Rawhide and F33 composes today. dnf itself seems to always pass
+this as a list or a tuple. The dnf API docs say "`pkg_types` is a
+sequence of strings determining the kinds of packages to be
+installed"; according to Python docs, lists, tuples and range
+types are "sequences", but sets are not, so technically we are
+out of bounds here. I believe this worked before this dnf commit:
+https://github.com/rpm-software-management/dnf/commit/4d991f61
+and upstream *could* probably tweak things to accept sets again,
+but it seems reasonable to fix it here.
