Created attachment 79018 [details] winecfg with patch
With the patch, the installation remains the same, but it makes winecfg very unhappy (screenshot attached).
that's not the intent for winecfg :-( can't repro here (even on fresh prefix) but that lower the likelyness subvolumes are the cause here (anyway if you have time, sharing a WINEDEBUG=+mountmgr could help maybe)
