Yeah.  gnodes are extensions of Suns vnodes which are extensions of the
traditional inodes.  On disk, you still have inodes, in the traditional
mode, but in memory there is an association with a "filesystem switch"
that allows supporting both NFS and Berkeley filesystems in a parallel
fashion.  In theory you could have any number of filesystems and types
are defined for BSD, NFS, System V, VMS, MSDOS and one or two others,
however DEC doesn't seem to have done much with these and has provided
no sample code that might allow a user to play with the facility.

See "man gnode" for a random sample of information.
