There was a problem hiding this comment.
There are quite a few more daemons in Dom0 (especially the newly split RRDD ones) that do not have this parameter.
We should eventually find a way to easily share the same config between multiple daemons.
For now this changes the existing MALLOC_CONF. We should probably have a separate PR that adds LD_PRELOAD+MALLOC_CONF to all the other OCaml daemons that don't have it yet, and use the settings from xenopsd-xc.service for that.
