Having recently switch from opkg to dpkg, I encountered some problems when
upgrading
packages which use the update-rc.d class. The problem are that update-rc.d :
a/ unconditionally calls "${INIT_D_DIR}/${INITSCRIPT_NAME} stop" in the prerm
script. This
is wrong, it should only do so when the prerm script is called for the
"upgrade" and
"remove" steps.
b/ unconditionally calls "update-rc.d $OPT ${INITSCRIPT_NAME} remove" in the
postrm
script. This is wrong, it should only do so when the prerm script is called for
the
"purge" step. However, "opkg" does not seem to support the "purge" step so I
suggest
calling it both for the "remove" and "purge" steps, after checking that the
init script no
longer exists.
You can find a description of how maintainer scripts are called by dpkg at:
http://www.debian.org/doc/debian-policy/ch-maintainerscripts.html
Attached is a patch which fixes both issues. I'd appreciate comments on this
one as
update-rc.d.bbclass is widely used.
