I see, thanks for your explanation.

A bit off-topic, but this would be a problem of the current
packaging and I remembered that Hilmar (?) once pointed out 
the problem (but I can't find out an email...).

Any user can mess up with running "updmap" without "--outputdir"
and also any related packages can mess up in their postinst etc.
with forgetting to add "--outputdir" appropriately in the current
teTeX packaging.

We might consider this issue, I guess.
