Already mounted, and working fine. I guess we can rule that one out.

I am doing all the testing on a VMware virtual machine, no ACPI, and no
buggy BIOS are involved. reboot doesnt hang, it just does nothing.

I am running another Linux virtual machine, which is a copy of the one I am
using for this testing, based on ttyLinux, only using the Busybox build of
ttyLinux, instead of doing my own build and that one reboots like a charm
(same boot scripts, and using the same vanilla kernel that I built
for the LFS system that I am using for all development and compilation
work). I have checked the busybox.links file of that build against mine, and
apart from a couple of irrelevant applets (hdparm, fdformat, for example),
there arent any applets that are available on the ttyLinux build that are
missing from mine (I went through the help of each missing applet to make

Finally, though I doubt its of any relevance, I am using wrappers instead of
hard or soft links to call busybox. Just in case, I called reboot and halt
directly by running "busybox reboot" and "busybox halt", and still the
system refused to reboot.
