Description Brian Lane 2013-02-05 01:30:29 UTC 
Description of problem:
Trying to use lorax to make a rawhide netboot.iso on an up to date Fedora 18 host.

lorax creates a directory tree for yum to install rpms into. Inside the chroot there are no dbus daemons and the tree is pretty bare. at-spi appears to be using gconftool-2 which blows up because it finds a blank /etc/machine-id file. I can reproduce this inside the chroot manually by running:

# export GCONF_CONFIG_SOURCE=xml:merged:/etc/gconf/gconf.xml.defaults
#  gconftool-2 --makefile-install-rule /etc/gconf/schemas/at-spi.schemas
process 6064: D-Bus library appears to be incorrectly set up; failed to read machine uuid: UUID file '/etc/machine-id' should contain a hex string of length 32, not length 0, with no other text
See the manual page for dbus-uuidgen to correct this issue.
  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

Comment 9 Ray Strode [halfline] 2013-02-14 16:50:06 UTC 
dbus requires a machine-id to be generated at startup. I think systemd does this with systemd-machine-id-setup
Comment 10 Ray Strode [halfline] 2013-02-14 16:51:46 UTC 
(s/startup/first startup/)
Comment 11 Ray Strode [halfline] 2013-02-14 18:32:03 UTC 
this is probably caused by this change:

Comment 12 Ray Strode [halfline] 2013-02-14 18:50:17 UTC 
talked to bcl.  I think the problem will go away if lorax scrubs the chroot environment, so bits from the host don't leak in (like DISPLAY and DBUS_SESSION_BUS_ADDRESS)
Comment 13 Brian Lane 2013-02-15 15:14:23 UTC 
Fix this by unsetting DISPLAY and DBUS_SESSION_BUS_ADDRESS in lorax.
