s390: missing cpuplugd

[bugproxy]

Requirement for : cpuplugd

This also includes a configuration file, man-page, and init script. The suggested package concept is a subpackage of the s390-tools.

This is a command and a set of rules in a configuration file to dynamically
enable or disable CPUs. For Linux on z/VM, you can also dynamically add or
remove memory.

Sample debdiff to integrate the cpuplugd daemon as subpackage of the s390-tools

looks good, on ubuntu makes sense to only ship the systemd unit.

[Dimitri John Ledkov (xnox)]

Why a sub-package? Would it be acceptable to ship this in s390-tools, but with systemd unit disabled? That way if people want to use cpuplugd they would modify the config as suitable, and enable it with `systemctl enable cpuplugd`.

[Dimitri John Ledkov (xnox)]

systemd unit should be shipped upstream, imho.

It is also fine to ship it with s390-tools. The systemd unit might be disabled. I will take care to add the systemd unit in the upstream s390-tools. Regarding the enablement of systemd units, can this be done on a per unit base? I mean, if you we add more and more systemd units in future, how to control enablement of particular systemd units only. (This is more a generic questions rather something on this BZ).

You can get the additional package via:
apt-get install s390-tools-cpuplugd

When it is installed, the service is enabled by default!! (OK, since it is a sub-package)

And cpu hotplugging works also as expected. Closed.
