怎样重现第一次启动（Only for Redhat）

重现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.
