I was checking my tumbleweed test to my slowroll test and was surprised to see it was the same.
I discovered that the slowroll iso did not put the slowroll repos on the machine - it put the tumbleweed repos.
To see what repos you have it is simple if it looks like this - it is tumbleweed and not slowroll:
TWSLOW:~ # grep http /etc/zypp/repos.d/*
/etc/zypp/repos.d/download.opensuse.org-non-oss.repo:baseurl=http://download.opensuse.org/tumbleweed/repo/non-oss/
/etc/zypp/repos.d/download.opensuse.org-oss.repo:baseurl=http://download.opensuse.org/tumbleweed/repo/oss/
/etc/zypp/repos.d/download.opensuse.org-tumbleweed.repo:baseurl=http://download.opensuse.org/update/tumbleweed/
/etc/zypp/repos.d/repo-debug.repo:baseurl=http://download.opensuse.org/debug/tumbleweed/repo/oss/
/etc/zypp/repos.d/repo-openh264.repo:baseurl=http://codecs.opensuse.org/openh264/openSUSE_Tumbleweed
/etc/zypp/repos.d/repo-source.repo:baseurl=http://download.opensuse.org/source/tumbleweed/repo/oss/

If it looks like this - it is correct and you have slowroll:
TWSLOW:~ # grep http /etc/zypp/repos.d/*
