Shouldn't packages for all PACKAGE_CLASSES be generated?

[Michael Opdenacker <michael.opdenacker@bootlin.com>]

Greetings,

I'm surprised by this behavior, which I didn't expect... I'm running 
"bitbake core-image-cmdline-full; bitbake generate-index" from Poky master.

with PACKAGE_CLASSES = "package_ipk package_rpm package_deb"...

find tmp/deploy/deb -name *.deb | wc; find tmp/deploy/rpm -name *.rpm | 
wc; find tmp/deploy/ipk -name *.ipk | wc
    1918    1918  129927
    1918    1918  135794
    5404    5404  393252

with PACKAGE_CLASSES = "package_rpm package_deb package_ipk"...

find tmp/deploy/deb -name *.deb | wc; find tmp/deploy/rpm -name *.rpm | 
wc; find tmp/deploy/ipk -name *.ipk | wc
    1918    1918  129927
    5404    5404  393606
    1918    1918  135584

with PACKAGE_CLASSES = "package_deb package_ipk package_rpm"...

find tmp/deploy/deb -name *.deb | wc; find tmp/deploy/rpm -name *.rpm | 
wc; find tmp/deploy/ipk -name *.ipk | wc
    5404    5404  376187
    1918    1918  135794
    1918    1918  135584

So, more packages are generated to the first item in PACKAGE_CLASSES.

It's expected to have the first item in PACKAGE_CLASSES that is used to 
generate the image, but I expected all packages to be generated for all 
package types anyway. Isn't this the expected behavior? Otherwise, how 
would you generate 3 types of feeds (rpm, deb and ipk) at the same time?

Cheers
Michaell
