重現firstboot.
If firstboot hangs, and then you reboot, and firstboot comes up again, does it
just hang again if you try this? Also, try going through firstboot (by adding a
user I guess). Then do this:
rm -rf /etc/sysconfig/firstboot
chkconfig --add firstboot
That will make firstboot come up again on the next reboot.
Seem it is only work against RedHat. But I am not sure very much about it.
