Yup, ok, so that's the problem.

Export information is scoped to the mount point for the file system being exported.  All of these entries in your exports file are basically redundant:

/usr/src        -network 10.73.0.0 -mask 255.255.0.0    -maproot=nobody
/usr/xsrc       -network 10.73.0.0 -mask 255.255.0.0    -maproot=nobody
/usr/pkgsrc     -network 10.73.0.0 -mask 255.255.0.0    -maproot=nobody
/usr/obj.aarch64        -network 10.73.0.0 -mask 255.255.0.0 -maproot=nobody
/usr/obj.pkgsrc.aarch64 -network 10.73.0.0 -mask 255.255.0.0 -maproot=nobody

...because they all are exporting the "/" file system.  This is allowed because all of the export attributes are the same.

To do what you want, you need to have a completely separate file system / mount point for /var/bulk.aarch64.
