I think the best approach is to add a bbappend file to your layer, which
installs your own config file.

If the config file is already in SRC_URI (like rsyslog's), it's just a
matter of creating a .bbappend like this:

  $ cat rsyslog_%.bbappend
  FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

, and adding your custom config file to the ${PN} directory (i.e.,
rsyslog/rsyslog.conf).  So, you'll have something like that in your
layer:

  recipes-extended/
  recipes-extended/rsyslog/
  recipes-extended/rsyslog/rsyslog/
  recipes-extended/rsyslog/rsyslog_%.bbappend
  recipes-extended/rsyslog/rsyslog/rsyslog.conf


Best wishes.
Mario

[yocto] Best practices for changing a conf file

[Crast, Nicholas]

Hi all,

I'm just looking for some advice on best practices. I want to change the 
configuration file for rsyslog called rsyslog.conf 
(poky/meta/recipes-extended/rsyslog), but there is a certain appeal to me of 
not changing the files in the meta directory. I like to keep those pristine and 
accomplish everything I need with recipes in a different layer. Is the best way 
to change this file to just go in and change that .conf file, or is there an 
easy way to use a .bbappend file to substitute my own configuration file?

Thanks,
-Nick
