There's a new patch in /n/sources/patch/kexportfs for two new cmds: ksrvfs and kexportfs. They're based on srvfs and exportfs but kexportfs uses the export system call. Russ did the modifications back in 2005:

% ls -l

--rw-rw-r-- M 314 rsc sys 9222 Nov 2 2005 kexportfs.c

--rw-rw-r-- M 314 rsc sys 1760 Nov 2 2005 ksrvfs.c

--rw-rw-r-- M 314 rsc sys 300 Nov 2 2005 mkfile

--rwxrwxr-x M 314 rsc sys 338 Nov 2 2005 xtest
