[oe] image.bbclass (rootfs_ipk.bbclass) should run package pre- and postinstall routines in package dependency order

[Hauser, Wolfgang (external)]

Hello,

I need to reconfigure some packages in my image, therefore I added some
additional packages for configuring.
I assumed, the packages are installed and configured in proper order
while creating an image by bitbake.

But at the time, the package pre- and postinstalls are executed in
alphabetic order
by searching the path ../usr/lib/opkg/info/ for *.preinst/*.postinst
while creating an image.

This cause problems because the install scripts of my configure packages
need some data from the
package(s) they depend on.

If I install the packages on the target, all is done well.

It may be better to resolve the dependency chain and use this list to
run the
pre- and postinstall routines of the packages in order of dependency.

It may be possible to create this dependency list by using opkg
whatdepends -A
<package>, or to use the bitbake internal order information of the
packages.

This should be a proposal for changing the behavior, I am not able to do
such a change, I don't have the necessary knowledge in bitbake at the
time.

Or is there an other solution, except pinning the needed order by naming
of the packages in the right alphabetic order.
