CONFFILES journey form source dir to rootfs


Alan
 

Hi,
I'm trying to understand how a conf file finds its way from source to
the rootfs.

The example is use is `journald.conf` from systemd.
The file originates from systemd source:
work/cortexa7hf-neon-vfpv4-senic-linux-gnueabi/systemd/1_234-r0/git/src/journal/journald.conf

In the environment is only mentioned as a part of the CONFFILES.
[output of `bitbake systemd -e` formated for readability]:

# $CONFFILES [2 operations]
# set /mnt/data/alan/work/senic-os/oe/meta/conf/documentation.conf:116
# [doc] "Identifies editable or configurable files that are
part of a package."
# override[systemd]:rename from CONFFILES_${PN} data.py:116 [expandKeys]
# "${sysconfdir}/machine-id
${sysconfdir}/systemd/coredump.conf
${sysconfdir}/systemd/journald.conf
${sysconfdir}/systemd/logind.conf
${sysconfdir}/systemd/system.conf
${sysconfdir}/systemd/user.conf"
# pre-expansion value:
# "None"
#
# $CONFFILES_systemd
# rename from CONFFILES_${PN} data.py:116 [expandKeys]
# "${sysconfdir}/machine-id
${sysconfdir}/systemd/coredump.conf
${sysconfdir}/systemd/journald.conf
${sysconfdir}/systemd/logind.conf
${sysconfdir}/systemd/system.conf
${sysconfdir}/systemd/user.conf"
CONFFILES_systemd="/etc/machine-id
/etc/systemd/coredump.conf
/etc/systemd/journald.conf
/etc/systemd/logind.conf
/etc/systemd/system.conf
/etc/systemd/user.conf"


The file successfully ends up at `/etc/systemd/journald.conf`.

Why isn't there an action in the environment showing the copying of
journald.conf
from `...git/src/journal/journald.conf` to
`${sysconfdir}/systemd/journald.conf`?


Disclaimer:
There were also some sed related actions with the file in the environment
which I dropped to reduce noise.

Be Well,
Alan
