[yocto] Errors with update-rc.d: /etc/init.d/XXX exists during rc.d purge (use -f to force)

[Richard Leitner - SKIDATA]

Hi Paul,
thank you for that hint and description of your workaround!
Looks like you've invested a little bit more time into working around this issue than me :-)

I've added "-f" to the update-rc.d.bbclass and now it's working like a charm:

diff --git a/meta/classes/update-rc.d.bbclass b/meta/classes/update-rc.d.bbclass
index d8cc342..dbb5781 100644
--- a/meta/classes/update-rc.d.bbclass
+++ b/meta/classes/update-rc.d.bbclass
@@ -33,7 +33,7 @@ updatercd_postrm() {
 if test "$D" != ""; then
        OPT="-f -r $D"
 else
-       OPT=""
+       OPT="-f"
 fi
 if type update-rc.d >/dev/null 2>/dev/null; then
        update-rc.d $OPT ${INITSCRIPT_NAME} remove


Nonetheless, I think there have to be a "cleaner" way to solve this issue than forcing the update-rc.d.
Maybe someone else has an idea how to solve this problem?

regards,
Richard
