Enable/disable service startup

Enable/disable service startup

Hi,

I am building Yocto 2.1 for PowerPC-64

I have bind and dhcpcd packages built in.

named service (from bind) gets started - but I do not want it started
dhcpcd service does not get started - but I would like to have it started

I would also prefer not to remove bind, because I need dig (dig, host, nslookup)

How to get services enabled/disabled ?

Also I do not want to change original recipes.

Kind regards,
Damir

You may be able to do it via a image post processing function.

hmm that may be a bug you need to see why it does not start

you have to change the code, doing finer packaging for bind where the daemon
gets packaged into package of its own and rest of the binaries e.g.
dig etc go into
another output package e.g. bind-extra or somesuch. then you just
include bind-extas
in your image.

That will be solved by not installing it, see below.

If you mean the dhcpcd recipe in meta-networking, it looks like that recipe 
doesn't have anything to enable it to start on boot (i.e. it does not inherit 
update-rc.d or systemd). If that's what you want you will need to do that 
either in the original recipe or use a bbappend.

Note that in some configurations (including our default) the dhcp client is 
started on demand by the networking scripts and thus doesn't need to be 
started as a service, but by default we are using dhclient for that and not 
dhcpcd.

The bind-utils package is already split out and packages dig and host, so I 
would suggest installing that rather than the main bind package. nslookup 
isn't being packaged at all, I suspect we are relying on the busybox stub 
version for that at least by default.
