[Buildroot] [PATCH 1/2] Rework of the init system

[Maxime Ripard]

Since we have now two uncompatible init systems, and we want only one of
them at the same time in use in the rootfs, we need to select a
particular init system. This patch also adds $(PKG)_INSTALL_INIT_SYSTEMD
and $(PKG)_INSTALL_INIT_SYSV hooks that are called when the matching
init systems are selected to install properly the init scripts of the
package.

[Buildroot] [pull request v3] Pull request for branch for-2012.08/systemd

[Maxime Ripard]

Hi Peter,

Do you intend at some point to take these patches ?

You *never* replied to any of these two patches, even though they both
have been floating around for more than half a year now, and this is
beginning to be quite frustrating.

Don't get me wrong, I'm not pushing them, I just want you to at least
acknowledge the existence of these patches and say if you are willing to
accept them or not.

Thanks,
Maxime

Yes, that's what I understood a bit later.
This is what is implemented in the third version of the pull request.

  You misunderstood my comment back then: I'm against _disabling_ the
busybox init.  The _enable_ should be kept.

  Arnout

I actually did so at first, and you asked me back then to remove it :)
(http://lists.busybox.net/pipermail/buildroot/2011-December/048541.html)

Anyway, I'm fine with both approaches here, so I'm fine adding it again :)

You added "Use " in front of sysv + systemd, but not busybox - And
"init" after busybox + sysv. I suggest you drop both so it becomes just
busybox/systemv/systemd.
