Hello,

I would like to customize an image I am developing based on core image minimal.

Particularly, I'd like to customize the files /etc/network/interfaces and /etc/inittab .

What should I do achieve that?

Thank you

Ottavio

Usually I do it by adding bbappend of corresponding packages to override original files, the interfaces is provided by init-ifupdown, the inittab is provided by sysvinit-inittab.

An example: http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-ppc/tree/recipes-core/init-ifupdown

Hi Ottavio,

There is more than way to do it. In your case I would use
ROOTFS_POSTPROCESS_COMMAND to modify files prior the creation of the rootfs.

You may:
- Create a .bbclass for your image inheriting core-image for example.
- Create a shell function to do some sed magic.
- Setup that function to run at rootfs creation.

Here is a example, I hope this helps :)

After that you can create a image recipe and inherit from that .bbclass. If
you don't want to create a .bbclass you can use this same aproach directly
on your image recipe :)

FYI there is a shortcut to creating these - the "recipetool appendfile" 
command. For example, say you have your desired custom inittab file locally as 
"myinittab" and you want the bbappend to be created in meta-mylayer then you 
would run:

recipetool appendfile meta-mylayer /etc/inittab myinittab

This will automatically determine which recipe is providing the file and how 
to overwrite it with your version. You do need to have built that recipe for 
this to work, but then that will already be the case if you have built the 
image beforehand.

Cheers,
Paul

It's always helpful to first check here: 
http://www.yoctoproject.org/docs/2.1/ref-manual/ref-manual.html

and here: 
https://www.yoctoproject.org/docs/1.6/bitbake-user-manual/bitbake-user-manual.html

But find an answer attached..

You should add a line
SRC_URI += "file://smb.conf"
that will copy a file from your "${THISDIR}/iris:" to ${WORKDIR}
and then..

..install this with "install -m 0644 ${WORKDIR}/smb.conf 
${D}${sysconfdir}/samba/smb.conf"

Also make sure that you have a directory ${D}${sysconfdir}/samba by 
adding the line:
install -d ${D}${sysconfdir}/samba

Hi all,

yet another newbie here stumbling around...

I'm not trying to find "any way" to do what I need.  I'm trying to learn how these thing sould be done in yocto.  Looks to mea s if I'm missing something basic.

I failed trying to follow this example.

I  have this samba_4.%.bbappend :
----
FILESEXTRAPATHS_prepend := "${THISDIR}/iris:"

do_install_append() {
    install -m644 iris/smb.conf ${D}${sysconfdir}/samba/smb.conf
}

And in the same directory a subdirectory "iris" which contrains the "smb.conf" I want to install.

Does not work.  Using `bitbake -c devshell samba` I found no copy of my "iris" directory.

Thanks so much.

/Jörg
