I fixed this issue in this way:
I modified the recipe replacing this:
------------------------------
pkg_postinst_${PN} () {
sed -e '/^hosts:/s/\s*\<mdns\>//' \
-e 's/\(^hosts:.*\)\(\<files\>\)\(.*\)\(\<dns\>\)\(.*\)/\1\2
mdns\3\4\5/' \
-i $D/etc/nsswitch.conf
}
pkg_prerm_${PN} () {
sed -e '/^hosts:/s/\s*\<mdns\>//' \
-e '/^hosts:/s/\s*mdns//' \
-i $D/etc/nsswitch.conf
}------------------------------
with this:
------------------------------
pkg_postinst_ontarget_${PN} () {
sed -e '/^hosts:/s/\s*\<mdns\>//' \
-e 's/\(^hosts:.*\)\(\<files\>\)\(.*\)\(\<dns\>\)\(.*\)/\1\2\3mdns
\4\5/' \
-i $D/etc/nsswitch.conf
}
pkg_prerm_ontarget_${PN} () {
sed -e '/^hosts:/s/\s*\<mdns\>//' \
-e '/^hosts:/s/\s*mdns//' \
-i $D/etc/nsswitch.conf
}
------------------------------
Basically, I added _ontarget_ as suggested by yocto error that says: "...
If the intention is to defer them to first boot,
> then please place them into pkg_postinst_ontarget_${PN} ()....".
In this way I can build the final image with LICENSE_CREATE_PACKAGE=1. Why?
I don't know. I didn't understand why there was this error.
However, the final result on the device when my os is running is different,
because my nsswitch.conf changes from "hosts: files myhostname mdns dns"
to "hosts: files mdns myhostname dns". Why? I don't know, however I
changed the regex in sed from "\1\2 mdns\3\4\5" to "\1\2\3mdns \4\5" to
restore the original result.
Why is it happening? Honestly, I don't know the reason. My solution worked,
but since I don't know why, I want to ask to someone more expert about
nsswitch.conf and in particular about pkg_prerm_ and pkg_postinst_ because
I really don't understand why I cannot change nsswitch without those and
why without LICENSE_CREATE_PACKAGE they are working also without adding
ontarget_, but with LICENSE_CREATE_PACKAGE = 1 the ontarget_ is required.
Please, can someone help about this? Or at least add in CC someone with
more experience about these topics.
Thank you.
