[yocto] useradd and one sysroot per recipe in pyro

[Laurent Gauthier]

Hi Christian,

In pyro the creation of users and group (using the useradd class) is
done during the package pre-installation.

So my best guess is that you could move the owner/group change in the
package post-installation as follows:

do_install () {
            (…)
            install -d ${D}${sysconfdir}/myappl
            install -d ${D}${localstatedir}/lib/myappl
}

pkg_postinst_${PN} () {
            chown -R myuser:mygroup ${D}${sysconfdir}/myappl
            chown -R myuser:mygroup ${D}${localstatedir}/lib/myappl
}

I hope this helps.

Laurent.
