[PATCH 0/4]fix support postrm/prerm at image creation time

[Hongxu Jia]

There are defects to support prerm/postrm at image creation time:
  1) gtk-icon-cache.bbclass:support postrm at image creation time
  2) update-rc.d:support postrm at image creation time
  3) libnss-mdns:support prerm at image creation time
  4) gtk-immodules-cache.bbclass:fix support postrm at image creation time

[YOCTO #3633] is about 1)gtk-icon-cache.bbclass

The following changes since commit 9f263a60e3521b800121a6f527a7b30dc9b62432:

[PATCH 1/4] gtk-icon-cache.bbclass:fix support postrm at image creation time

[Hongxu Jia]

The gtk_icon_cache_postrm failed at image creation time because ${D} is not
assigned as the prefix of icondir.

I think you can just exit 0 here and let the hook in intercept-scripts
directory do the rest. The hook was added in the postinst and it will
properly call gtk-update-icon-cache. If you look in the log.do_rootfs
you'll see that the intercept scripts are run at the end (just look for
"Running intercept scripts"). So, I don't think you need to do this loop
here. Besides, it will be called for every postrm and running
gtk-update-icon-cache is not cheap...

Thanks,
Laurentiu

Ok, I will work on it to let the hook in intercept-scripts do the rest.

I just realized that, in order for the hook to be installed, the postint
scriptlet has to be run in the same do_rootfs session, otherwise the
hook will not be installed... In which case you might want to do that in
the postrm itself (like it was done for postinst).

Laurentiu

Some packages are removed at image creation time? Why is postrm
executed?

And why don't use use $D in both cases (when empty and not empty) those
2 for cycles look the same.

Again looks the same why not use $D/etc/nsswitch.conf in both cases?

I think that  test $D to explicitly make a distinction between the build 
time
and run time, it's better for others to notice the difference.

But there isn't any difference if I'm looking correctly.

Surely you still want to run the postrm, and by exiting with 0 you're
not deferring it.  Can't this use the same logic as the postinst to
run on both build machine and target?

No problem, I will use the same logic as the postinst to do that.

[PATCH V2 0/4]fix support postrm/prerm at image creation time

[Hongxu Jia]

There are defects to support prerm/postrm at image creation time.
Change with V1:
  1) gtk-icon-cache.bbclass: install hook instead of calling
     gtk-update-icon-cache directly.
  2) libnss-mdns: delete test $D, directly use $D/etc/nsswitch.conf.
  3) gtk-immodules-cache.bbclass: postrm use the same logic as the
     postinst.

[YOCTO #3633] is about 1) gtk-icon-cache.bbclass

The following changes since commit 9f263a60e3521b800121a6f527a7b30dc9b62432:

[PATCH 3/4] libnss-mdns:fix support prerm at image creation time

[Hongxu Jia]

The pkg_prerm_${PN} failed at image creation time because $D is not assigned
as the prefix of "/etc/nsswitch.conf"
