*preinst use "-f remove" to remove any links in the /etc/rcrunlevel.d
but this will make user cannot keep previous init script link
after upgrade
eg: user disable one service before upgrade, after upgrade, service
could be started since during preinst, all link have been deleted, so
postinst may create the link to start service.
remove preinst to keep previous links, so that after upgrade, if any
link existed for the package, postinst will not create new start/stop
links.
(note: patch of support enable/disable function of update-rc.d send
to yocto mail list today)
*remove -f for postinst, previously, recipe keepalived use remove during
postinst, so need this -f, but remove in postinst is not proper, recipe
keepalived have fixed this problem, so remove -f.

Add Ross and Phil who have been committers for update-rc.d.
The changes seem sensible to me but the commit logs need some polish
to be more clear. I'll help Sandy with that later if needed.

From: Changqing Li <changqing.li@windriver.com>
* update-rc.d has added support of enable/disable options, which are
expected to keep the previous configuration even after upgrade the packages.
With support for these options, it will only create start/stop link
when there are none, or it will keep the previous configuration.
Our preinst uses "-f remove" to remove any links under the /etc/rcrunlevel.d
which is conflicting behavior with disable/enable options, so remove it.
For example, if a user disabled one service before upgrade,
then after upgrade the service could be started. This happens because during preinst,
all links have been deleted, then postinst may create the link to start service.
With this change, we remove preinst and therefore keep the previous links
so that after upgrade, if a link existed for the package, then the postinst
will not create new start/stop links.
* remove '-f' for postinst. Previously, the keepalived recipe used 'remove'
during postinst, so we needed the -f, but now the keepalived recipe has fixed
this problem, so it's safe to remove '-f'.

Add support of enable/disable options, refer
https://manpages.debian.org/wheezy/sysv-rc/update-rc.d.8.en.html
With support of these options, the usr can never change an existing
configuration even after upgrading a package. The program will only
install links if none are present, otherwise, it will keep
the previous configuration.
preinst in update-rc.d.bbclass will delete all the links under
rcrunlevel.d, this behavior now conflicts with enable/disable
options. so remove preinst from the update-rc.d.bbclass

Thanks, Richard.
I see this patch have merged into repo update-rc.d. But in this patch
series, there are
2 patches, please also help to review the other one. Maybe this patch
series seems a little messy
in the mail. I will reply on the other patch for you to pick it out easily.

This patch needs to go to OE-Core for the bbclass part. The
documentation piece needs to be separated out as its a different
repository. Also doesn't it depend on the change I just made to the
update-rc.d repo so there will be a SRCREV that needs to be updated
that this depends on?
Thanks,
Richard

I will split the oe-core and document part.
without change in update-rc.d.bbclass, new function add in update-rc.d
repo will not work.
since preinst in update-rc.d.bbclass will delete all the links under
rcrunlevel.d, this behavior
conflicts with enable/disable options.
and you're right, I also need to update SRCREV of update-rc.d.bb in
oe-core repo.
Thanks.
I will send it later.
