As far as I can see, '$shtdwn$.reg' is not prefixed with a dot or anything, so
that can't be the problem here... Right?

The problem is the installer expects the file to be hidden, in the Windows way,
e.g., not a '.', but given the hidden attribute, which Wine does not support.

You said:

I thought this was the way Wine does it now :)
What about this: Wine gets (for case insensitivity) a solution like ciopfs: all
files are stored in lower case, and then Wine keeps a database file (sqlite or
so?) containing the original filename and other non-ext properties, like
whether they are hidden. Using SQLite, it wouldn't be too slow; Wine doesn't
need to read all files in the directory since the files are lowercase.
It only needs to search if the lowercase file does not exist, in which case it
does search and if it finds a file, it renames it to lowercase and adds it to
the database to speed up future searches; this is necessary to merge from older
Wine versions. This solution will only be noticeably slow when an application
continuously asks for a non-existent file; and it will be just as slow as the
old Wine solution. It will also be backwards compatible, only older versions of
Wine will not return the original filename but the lower case one (since they
search the whole directory anyway).
Any objections, except that SQLite support is needed?

You forgetting that Wine doesn't have it's own FS. Nothing prevents a program
outside of Wine to copy a file into "C:".

Also what about the rest of the root file system (/)?

This can only be supported for files created from within Wine. The actual
attributes can be stored in the special hidden file in the same directory
(preferred) or the globally (not portable).

That's only a real problem as far as that program only writes lowercased
files... I think that's an acceptable thing, isn't it?

It would just work like wine works now; readdir() I guess. :)

Ok. I agree the main flaw in the idea (the fact that from outside wine, the
case insensitivity isn't enforced) makes it a no-go. I could implement this
special hidden file support (or even generally, extra file flag support) in
Wine, but it may take a moment since I'm totally not accustomed to Wine's
source, I've never seen a bit of it.

If there's anything I should read about the plans related to this before I
start, please drop me some links and I'll get coding. (that's apart from the
normal stuff a beginning Wine developer should read, I can find those on my own
;) )

maybe one could use xattr to store a user.wine.hidden
attribute with the file... but Ubuntu doesn't ship with
/home mounted with user_xattr, so that's not likely to
fly any time soon.
