[OE-core] useradd.bbclass question

[Andreas Müller]

Hi,

on one of my build machines useradd.bbclass seem to use the UID/GID of
build host. On other machines useradd works correct.

I have the follwing in gdm:

<snip>
do_install_append() {
    ...
    chown -R gdm:gdm ${D}${localstatedir}/lib/gdm
    chmod 0750 ${D}${localstatedir}/lib/gdm
}

...

USERADD_PACKAGES = "${PN}"
USERADD_PARAM_${PN} = "--system --no-create-home --home
${localstatedir}/lib/gdm --user-group gdm"
<snip/>

In sysroot /etc/group I see
gdm:x:990:

In sysroot /etc/group I see
gdm:!:993:990::/var/lib/gdm:

The folder in packet/image has IDs 42:42 which is taken from build host.

Any ideas what causes this - or is there something wrong with chown at
do_install?
