I tested it on Mac OS X with the default file system i.e. ~somewhat~
case-insensitive. What I did not do was install the files into the TL
system-wide tree and test that way. So it breaks for me now, too. If I
have the fd file in the same directory as my document, no problem. If I
have the fd file in my home texmf tree, also no problem. So I didn't
see the issue during testing - the documentation compiled fine etc.

Something like this came up for the arrows and bullets package, too. I
altered adfsymbols so that the fd files are entirely lower-case and
that seemed to work.

My instinct is therefore to rename the fd file to uornementsadf.fd.
However, I don't really understand what is going on here so this isn't
necessarily the best thing to do. It is complicated by the fact that in
the adfsymbols case, things which worked for me didn't work for a user
on a different system, so I can't just assume that if I fix it for OS
X, it will work generally.

fontinst seems to always use all lowercase for fd file names which
makes me think the solution should work generally. Is that correct?

Sorry for the delay - just as I disappear from email for a couple of
days, up crops a problem with something I'm responsible for!

Thanks,
Clea
