Ok, this kills my approach. I didn't know that.

I personally have the need for one special NFS mount to behave case
insensitive with the Samba semantics. I.e. I have that filesystem NFS
mounted and write to it, while most other clients have it SMB mounted (mostly
read only). There are some pitfalls where my scripts accidently create
filenames differing in case only - and boom - the SMB clients can't read
Not knowing the different semantics I searched for the most general solution.

Yes, but: creating a file should be a simple creat() call. Only the kernel
can provide this with atomic semantics if case-only-different file names are

Sure, it isn't. Samba is a total loss when it comes to performance, mainly
due to it being userland only. See how NFS servers loose when implemented in
userland. You can easily outperform any NetBSD file server in a SMB
environment with 1/10 the hardware performance by installing Win2K.
But this is completely off topic now.
Sorry for the waste bandwitht, thanks for all the enlightenment
