[yocto] ALTERNATIVE_TARGET, ALTERNATIVE_PRIORITY problem

[Joseph Andrew de la Peña]

Good day Yocto Community,

I would like to ask what's wrong with my implementation with
update-alternatives:

=================

*bar_git.bb <http://bar_git.bb/>:*

PACKAGES =+ "${PN}-bar1 ${PN}-bar2 ${PN}-bar3"
RPROVIDES_${PN}-bar1 = "bar"
RPROVIDES_${PN}-bar2 = "bar"
RPROVIDES_${PN}-bar3 = "bar"

ALTERNATIVE_LINK_NAME[bar] = "${datadir}/foo/bar"

ALTERNATIVE_${PN}-bar1 = "bar"
ALTERNATIVE_TARGET_${PN}-bar1 = "${datadir}/foo/bar1"
ALTERNATIVE_PRIORITY_${PN}-bar1 = "99"

ALTERNATIVE_${PN}-bar2 = "bar"
ALTERNATIVE_TARGET_${PN}-bar2 = "${datadir}/foo/bar2"
ALTERNATIVE_PRIORITY_${PN}-bar2 = "98"

ALTERNATIVE_${PN}-bar3 = "bar"
ALTERNATIVE_TARGET_${PN}-bar3 = "${datadir}/foo/bar3"
ALTERNATIVE_PRIORITY_${PN}-bar3 = "97"

inherit update-alternatives

*packagegroup-foobar.bb <http://packagegroup-foobar.bb/>:*

RDEPENDS_foobar = "bar"

=================

The end result is always bar3 is present and bar is pointing to bar3. I
never get bar1 being present which is the result I want.

Please do recommend how will I properly use ALTERNATIVE_TARGET and
ALTERNATIVE_PRIORITY.

Thanks,
Joseph
