clarify instructions for package feed installation

clarify instructions for package feed installation

[Peter A. Bigot]

Following the instructions in the 2.4.2 mega-manual section 4.21.4 I set
in local.conf:

     PACKAGE_FEED_URIS = "http://192.168.65.22/oe/rpi3-sumo"
     PACKAGE_FEED_BASE_PATHS = "rpm"
     PACKAGE_FEED_ARCHS = "noarch cortexa7hf_neon_vfpv4 raspberrypi3"

and run this command:

     bitbake package-index

This produces a repodata directory in the deploy/rpm directory, sibling
to the arch directories.

drwxr-xr-x 2 pab pab 516096 Mar 15 12:26 cortexa7hf_neon_vfpv4
drwxr-xr-x 2 pab pab  24576 Mar 15 12:55 noarch
drwxr-xr-x 2 pab pab 262144 Mar 15 12:26 raspberrypi3
drwxr-xr-x 2 pab pab   4096 Mar 15 15:02 repodata

However, the repo file generated by the PACKAGE_FEED variables causes
dnf on the target to fetch repodata from inside each arch directory:

192.168.65.117 - - [15/Mar/2018:14:03:18 -0500] "GET 
/oe/rpi3-sumo/rpm/noarch/repodata/repomd.xml HTTP/1.1" 404 481 "-" 
"dnf/2.7.5"
192.168.65.117 - - [15/Mar/2018:14:05:51 -0500] "GET 
/oe/rpi3-sumo/rpm/raspberrypi3/repodata/repomd.xml HTTP/1.1" 404 487 "-" 
"dnf/2.7.5"
192.168.65.117 - - [15/Mar/2018:14:05:51 -0500] "GET 
/oe/rpi3-sumo/rpm/cortexa7hf_neon_vfpv4/repodata/repomd.xml HTTP/1.1" 
404 496 "-" "dnf/2.7.5"

This doesn't work.  I end up having to change the repo file to eliminate
the architectures.

Is this a problem specific to RPM, or am I doing something wrong?

Thanks.

I think the documentation is misleading here. 'bitbake package-index' 
generates a single index for all of the architectures in the deploy/rpm 
directory, so if you need individual feeds for specific architectures, 
you need to generate them yourself with a custom recipe. Or if you're 
okay with having a single index, just drop the PACKAGE_FEED_ARCHS setting.

CC Scott, so we can add a note for RPM feeds in the docs here.

Thanks; that makes sense.  A documentation note that PACKAGE_FEED_ARCHS 
should only be used if indexes are generated a different way would be 
worthwhile.  AFAICT the only time identifying specific architectures is 
useful is in filtering irrelevant candidates when multiple architectures 
are present. It's not immediately obvious how to put multiple 
incompatible archs into the same hierarchy anyway unless something 
automatically reconciles the companion noarch packages that get produced 
in builds for different MACHINEs.
