[Buildroot] [PATCH v2 1/1] package/systemd: remove SysV and utmp compatibility feature

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

Norbert, All,

On 2020-07-18 01:43 +0200, Norbert Lange spake thusly:
> Systemd enabled compatibility with SysV services and utmp
> by default, none of which is needed for buildroot as the packages
> will install only the files for the chosen init system.

At first, I thought that we may want users to be able to use their dusty
init script, carefully crafted over decades of patient tweaking and
twitching, especially fr out-of-tree packages (br2-extermal).

However, it turns out that this is not possible: systemd requires both
/etc/init.d *and* /etc/rc.d to exist to provide SysV emulation. And as
Thomas said, /etc/rc.d does not exist in Buildroot.

As such, SysV support has never been functional in Buildroot, and we
can't easily make it so.

So, applied to master.

However, this patch again does too many things: disable sysv support and
disable utmp support.

I've split the two in two commits, expanded the two comit logs, and
applied to master. Thanks.

Regards,
Yann E. MORIN.
