Mads,

thank you for your reply. I did not commit the new .hgsub to the tip
of the default branch. The developers working on that particular repo
"abandonned" the default branch a while ago, and kept working on
another branch called "UNIVERSAL" and that is where I changed the
.hgsub file.

I did a dummy merge with the default branch (since de tip of default
was an ancestor of the UNIVERSAL branch) and tried again and now the
clone uses the new .hgsub mappings!

I was not aware of the rule that subrepo mappings are always taken
from the tip of the default branch. Is that the case?

Thanks,

Angel
