[Xen-devel] [PATCH v3 7/7] systemd: add support initial xen systemd service files

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

These are originally based on the Fedora systemd files.

Changes made:

  * allow for xenstored configuration through *either* of these
    configuration files:
        - /etc/sysconfig/xenstored
        - /etc/default/xenstored
    The /etc/default/xenstored will let debian based systems do
    the same, while SUSE/OpenSUSE/Fedora/RedHat can keep on chugging
    with sysconfig
  * generalized path meta @VARIABLES@ which are configuration specific
  * uses new xenstore-read -l 30 -s prior to doing letting things rip
  * defines systemd socket for xenstored
  * ensures we create the run directory as most systems will likely
    be using a tmpfs for run dirs for the pid files
  * Some systems define the selinux context in the systemd Option for the
    /var/lib/xenstored tmpfs:
        Options=mode=755,context="system_u:object_r:xenstored_var_lib_t:s0"
    For the upstream version we remove that and let systems specify the
    context on their system /etc/default/xenstored or /etc/sysconfig/xenstored
    $XENSTORED_MOUNT_CTX variable
  * defines a modules-load.d for us
  * takes advantage of the shared xendomains helper for the xendomains
    service
  * Add the new dom0 that gets kicked off for disk backend access into
    its own systemd service associated to xen

We end up with these systemd files:

General requirements:

  * proc-xen.mount
  * var-lib-xenstored.mount

xenstored:

  * xenstored.socket
  * oxenstored.service
  * xenconsoled.service
  * xen-qemu-dom0-disk-backend.service.in

Optional:

  * xendomains.service
  * xen-watchdog.service

As for integration with xen, we house keep all the systemd files
under a new directory tools/hotplug/Linux/systemd/ and will be targetted
by default when building on Linux systems (CONFIG_Linux) given the low
overhead of only having to only sed the meta @VARIABLES@. The systemd
files will be sanitized for meta @VARIABLES@ upon the all make target by
default, and installed upon the install target. Systems that do not use
systemd will still have these files installed but can still just use the
old LSB init scripts; if they happen to get systemd they can easily
switch to it. The changes above only apply to systems that use systemd.

If you don't specify a prefix you will end up with the services
files under /usr/local/lib/systemd/system/ by default, and systemd
modules-load.d conf files under /usr/local/lib/modules-load.d/ which
systemd does look for (although it seems this is not documented).

Distributions are expected to provide their /usr/ prefix to end up in
the more generic location upon distribution install at
/usr/lib/systemd/system/ and /usr/lib/modules-load.d/ respectively.

Since we have a systemd socket defined for xenstored we may be able to
eventually remove our sanity check of tesing access to xenstored with
'xenstore-read -l 30 -s' but we keep it for now.
