Yes, that's correct.  I already have the target type encoded in the symlink,
but at the moment it infers it from the type of the target:

https://github.com/wine-staging/wine-staging/blob/a11594e19e035f3184ab46a04e0272580e9d7762/patches/ntdll-Junction_Points/0007-ntdll-Add-support-for-absolute-symlink-creation.patch#L244

The reason for that is that I don't know how to convert
SYMBOLIC_LINK_FLAG_DIRECTORY into a flag/option/whatever for the reparse point,
as that's not in the documentation:
https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-fscc/b41f1cbf-10df-4a47-98d4-1c52a833d913

I used to have it use the information from the opened handle, but I discovered
looking into this that that either stopped working or that I had incorrectly
believed that it was working before:
https://github.com/wine-staging/wine-staging/blob/a2ca43d98b3a45ae3bd66e8c71090b42e18c9bdd/patches/ntdll-Junction_Points/0007-ntdll-Add-support-for-absolute-symlink-creation.patch#L244

Hopefully this is something simple and I'm just not seeing it at the moment,
any thoughts?
