@kazuhiko it seems tests are not happy because trafficserver, which is shared references luajit, which is not shared, this is the :

RuntimeError: Software hash present in signature /srv/slapgrid/slappart0/srv/testnode/cvt/inst/test0-0/tmp/shared/trafficserver/5d4eae3ceabc0d768ae1d5022fb4b8bb/.slapos.recipe.cmmi.signature

that we can see here.

On other tests (for exemple this one), there's also a

RuntimeError: /srv/slapgrid/slappart0/srv/testnode/cvt/inst/test0-0/tmp/shared/trafficserver/5d4eae3ceabc0d768ae1d5022fb4b8bb/libexec/trafficserver/tslua.so has some not found libraries:
	libluajit-5.1.so.2 => not found

I guess this is because rpath is missing, I did not try, but something like this could fix:

The patch I suggested was not enough, I needed tests for another task, so I applied the fix on master to repair 6a9beec3 I hope that's OK

[Kazuhiko Shiozaki]

@jerome oh I didn't notice, thanks for your fix !
