[Buildroot] [PATCH 0/7] [RFC] Introduce services as a (long-term) replacement for _INSTALL_INIT_(SYSV|SYSTEMD) (branch yem/services)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

Following up on Gustavo's proposal [0] on a clean up on our init
scripts (and eventually our systemd unit files), here is an *RFC*
series that tries to implement Gustavo's idea.

The series is split in four parts:

  - patches 1-3 are preparatory work, and not much interesting in the
    Grand Scheme of Life;

  - patches 4-5 introduce a generated kconfig snippet, that contains
    the list of services for each enabled packages, that the user can
    enable/disable at will, directly from the menuconfig (for now, the
    default is that all services are disabled, that can be changed
    later);

  - patch 6 is the guts that installs the service files:
    - installs the service's startup script,
    - enables/disables the service,
    - installs the service's configuration, if it exists;

  - patch 7 is just an example (with empty scripts) of how to declare
    services in a package.

To be noted:
  - the code will need some revamp; this is just meant to be an RFC!
  - only sysv init is handled for now
  - this is by far incomplete even for the sysv case
  - the /etc/config/ part has been left out for now; it would anyway
    most probably provided via a rootfs-overlay
  - the manual part is missing
  - there are typoes all over the place :-/

As usual: on your mark, get set, comment! ;-)
