└─>Use 96-bit Coda file identifiers
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
A new kernel-userspace API had to be introduced for Coda v6.0
to support larger 128-bit file identifiers as needed by the
new realms implementation.

However this new API is not backward compatible with older
clients. If you really need to run the old Coda userspace
cache manager then say Y.

For most cases you probably want to say N.
