We are adding better support for systemd in 0.25. The ticket is MESOS-3425. Naturally this is still somewhat experimental, but we would love your feedback. We will add some documentation on recommended setups on systemd.
With the changes going into 0.25 you should be able to launch your slave with > Killmode=control-groups > Delegate=true The slave should be able to be restarted while the executors remain running un-interrupted. This requires systemd version 218+, or a patched implementation of prior version. You can see the related ticket for more information about supported patched packages by RHEL, etc.: MESOS-3352 Joris On Wed, Sep 23, 2015 at 8:11 AM, Brian Devins <badev...@gmail.com> wrote: > Are you using systemd?
