I built a derivative of cloud9-gnome-image/Angstrom-1.4 for the
Beaglebone Black on an Ubuntu 12.04 host.
When I boot, I get a popup window with the text:
"Could not update ICEauthority file /var/lib/gdm/.ICEauthority"
This appears because /var/lib/gdm is not owned by gdm.
Instead it is owned by 115:125
I manually changed the owner and rebooted, and this time I did not get
the error message.
I tracked down why:
The recipe for gdm in
meta-openembedded/meta-gnome/recipes-gnome/gdm_2.32.2.bb contains:
------------------------------------------------------------------------------
do_install_append() {
...
chown -R gdm:gdm ${D}${localstatedir}/lib/gdm
chmod 0750 ${D}${localstatedir}/lib/gdm
...
}
------------------------------------------------------------------------------
Problem with this approach is that the chown command is using the
user:group of the host .
If I do
<host> # cat /etc/passwd | grep gdm
I get:
gdm:x:115:125:Gnome Display Manager:/var/lib/gdm:/bin/false
If I do the same on the target I get:
root@beaglebone:~# cat /etc/passwd | grep gdm
I get:
gdm:x:997:993::/var/lib/gdm:/bin/sh
so I think that setting the user:group must be done in a postinstall task.
