update various gentoo bits 
Update an rc-update call to only be made if running openrc instead of
all gentoo profiles (systemd does not have rc-update).

Add python3-pyyaml package mappings.

Update serial console to support multiple arches.

Update open-iscsi and open-isns keywords (looks like upstream merged
some musl fixes).

Update the kernel and initramfs file name globs for the
gentoo-kernel-bin usage.

svc-map

Map service names to distro specific services.

Provides the following:

  • bin/svc-map

    usage: svc-map [-h] SERVICE

    Translate service name to distro specific name.

    optional arguments:

    -h, --help show this help message and exit

  • Any element may create its own svc-map YAML config file using the one of 3 sections for the distro/family/ and or default. The family is set automatically within svc-map based on the supplied distro name. Families include:

    • redhat: includes centos, fedora, and rhel distros
    • debian: includes debian and ubuntu distros
    • suse: includes the opensuse distro

    The most specific section takes priority. Example for Nova and Glance (NOTE: default is using the common value for redhat and suse families)

    The key used for the service name should always be the same name used for the source installation of the service. The svc-map script will check for the source name against systemd and upstart and return that name if it exists instead of the mapped name.

    Example format for Nova:

    nova-api:
  default: openstack-nova-api
  debian: nova-api
nova-cert:
  default: openstack-nova-cert
  debian:  nova-cert
nova-compute:
  default: openstack-nova-compute
  debian: nova-compute
nova-conductor:
  default: openstack-nova-conductor
  debian: nova-conductor
nova-consoleauth:
  default: openstack-nova-console
  debian: nova-console

    Example format for Glance:

    glance-api:
  debian: glance-api
  default: openstack-glance-api

    If the distro is of the debian family the combined services file would be:

    nova-cert: nova-cert
nova-compute: nova-compute
glance-api: glance-api
nova-conductor: nova-conductor
nova-api: nova-api
glance-reg: glance-reg
nova-consoleauth: nova-console

    If the distro is of the suse or redhat families the combined services file would be:

    nova-cert: openstack-nova-cert
nova-compute: openstack-nova-compute
glance-reg: openstack-glance-registry
nova-conductor: openstack-nova-conductor
glance-api: openstack-glance-api
nova-consoleauth: openstack-nova-console
nova-api: openstack-nova-api

    Example commands using this format:

    svc-map nova-compute

Returns: openstack-nova-compute

svc-map nova-compute

Returns: openstack-nova-compute

svc-map nova-compute

Returns: nova-compute

  • This output can be used to filter what other tools actually install (install-services can be modified to use this for example)

  • If you pass more than one service argument, the result for each service is printed on its own line.

  • Individual svc-map files live within each element. For example if you have created an Apache element your svc-map YAML file should be created at elements/apache/svc-map.
