# Node ID 16aa4b417c6b97c9378b4b44df57fc3bd3b1d2be
# Parent 353404fe850c40569d04972ccc8929dc9948b9d8
[XEN] Clean up shutdown handling and ignore opt_noreboot if dom0
shuts down cleanly. The option is intended only to retain information
on the local console in case of a crash.
Based on a patch from Muli Ben-Yehuda <muli@xxxxxxxxxx>
Signed-off-by: Keir Fraser <keir@xxxxxxxxxxxxx>
