aa2d840a3b compat-rules: fix warning: "label ‘out’ defined but not used" in path_id_compat.c
- Restore 61-persistent-storage-compat.rules that was mistakenly
dropped during the merge of v248.

- Create /run/lock/subsys again (bsc#1187292)
The creation of this directory was mistakenly dropped when
'filesystem' package took the initialization of the generic paths
over.
Paths under /run/lock are still managed by systemd for lack of
better place.

- Drop systemd's dependency on udev (jsc#PM-2677)
In some environments (i.e. containers) udev is usually not necessary
but pulls in unnecessary packages.

- Now that chkconfig/insserv are history, let's implement the strict
minimum in systemd-sysv-install to enable/disable SysV init scripts
(bsc#1186595 bsc#1186359)
Indeed there's no much point in dropping SysV support completely
until upstream will do especially since 3rd party applications such
as vmware still rely on it, see bsc#1186359).

- Allow the sysusers config files shipped by systemd rpms to be
overriden during system installation (bsc#1171962)
- While at it, add a comment to explain why we don't use
