Taking the GENERIC kernel and commenting out MSDOSFS, CD9660{,_ROOT}, PROCFS,

Browse Source 
NFS_ROOT will produce kernel that cannot mount a UFS /.

Vfs type numbers must be distinct from VFS_GENERIC (and VFS_VFSCONF, but
that has the same value and should go away).

The problem happens because NFS is the first vfs (in sys/conf order) so it
gets type number 0 and conflicts harmfully with VFS_GENERIC which is also 0.
The conflict is apparently harmless in the usual case when another vfs
gets type number 0, because nfs is the only vfs that has sysctls.
