I've considered adding a feature to power off the client
machines after imaging, and I've seen that the busybox
halt and poweroff don't actually shut off the power,
at least on a Dell D600 notebook with the 2.4.26 kernel.
On the busybox mailing list, someone discussed using:
echo 5 > /proc/acpi/sleep
This seems to work OK in my testing from the busybox shell
within udpcast session, without actually running an imaging session.
In the case of nothing being mounted, is there any potential
for damage to the client system by powering off this way inside
I can't think of any problems, but I thought I should check
if anyone knows of anything that might not be flushed
from memory, etc., immediately after a udp-receiver operation.
