[PATCH] systemd: Remove init.d dir if systemd unit file is present and sysvinit not a distro feature

[PATCH] systemd: Remove init.d dir if systemd unit file is present and sysvinit not a distro feature

[Shakeel, Muhammad]

From: Muhammad Shakeel <muhammad_shakeel@mentor.com>

If systemd is supported DISTRO_FEATURE and sysvinit is not and also if
systemd_unitdir contains a service file(s) then no need to keep init.d scripts
for sysvinit compatibility.

why only .service?  Other systemd files (.socket, .mount, .path, ...)
can also replace initscripts.

Other systemd unit files are normally accompanied with a .service file 
(this is just I observed and not mandatory).

If we come across any package which is not providing .service file but 
only some other type of systemd unit file for initscripts replacement 
then we can always add check for that type.
According to systemd documentation there can be 10 types of systemd unit 
files and checking for all here can be a little overhead.

Thanks

Would it work to simply check for any files instaled into systemd_unitdir?

Cheers,

Agreed - the list of file types has grown over time so we'd been
constantly chasing systemd, and it's not like anything else is dropped
into this directory.

Ok, I will send a V2 with updated check.

Hi,

I just tried this patch out.
It resulted in the following warning.

WARNING: busybox: NOT adding alternative provide /etc/init.d/syslog: 
/etc/init.d/syslog.busybox does not exist

I know this warning is harmless. But it's still somewhat misleading. So 
are we going to do something about it?

Yes, I am going to send a V2 and that will handle this warning.

Thanks
